Hello,

I just had my webaster to enable PHP 8 for the community. We got an error 500 after that. 

We enabled 8.0 for WordPress and another domain in the same server and all went smoothly. It didn't work on Invision Community. We've reversed the installation to the previous php version and works fine again. 

I need help on this. 

Thanks

Same problem from my side, I had to get back to PHP 7.4. Have you solved this? And if so, how?

Thanks!

Hello,

I have the block "Clubs" in the home page of my website. I have found an issue (bug?) with that. These are the settings I have:

And this is what I see:

Everything correct here, but 9 minutes ago I have added a reply in the club "TEST 1", and the club "TEST 2" is still listed first. Clubs are sorted by latest activity, so TEST 1 should be ranked first. This will happen (according to my previous experience) in 30-40 minutes from the latest reply. I guess in a few minutes TEST 1 would finally get to the first position and TEST 2 to the second position, but it will be more than 30 minutes after the reply to a thread in that club. I would need this to happen in real time or maximum 1 minute after the latest reply. Is there any way I can do that?

Also, a suggestion: it would be nice if the "Sort by" options in the Clubs bloc would be the same of the Topic Feed block:

"Recently Updated" here means the latest reply. "Latest activity" in the club means, I guess, latest reply (99% of the times), or a user who joined the club (1% of the times). Maybe something else is considered as "activity"? Maybe a reaction? Anyway, it would be great to have the option to sort clubs just like the "sort by: Recently Updated" works for the Topic Feed block.

Thank you!

You would really need to contact the author of that code for support. We would not generally issue support for custom items

Thanks! @Kirill Gromov is the author. He is in holidays now, I hope he will be able to fix this when he will be back. 🤒 @Kirill Gromov Please look at @Daniel F link, maybe this helps you to fix the block. Thanks!

Hello,

I would need exactly the same. Any way this can be implemented in the future? And can this be realized as a custom block?

Thanks!

The block with ID 165 seems to be the evil one.

Based on the error message which mentions usort, I'm betting my money on some weird usort usage, PHP8 got here much more strict, pls see https://wiki.php.net/rfc/stable_sorting

Hello @Daniel F, I have copied in the post above the code for that block. I have no clue how what to edit there and I would not want to damage the code. Maybe it is just a matter of changing something in the code and the problem would be fixed?

Thank you!

You are right, that is the "evil" one. This is a custom block made by one of the IPS users. By the way now he is in holidays 😄 Here is the content, can you please tell me if something needs to be changed to fix this?

Thanks!

This is because there is PHP code which is not comparible with PHP 8. With the one above, have you checked that test page? It looks like you have a custom block on there which is causing you issues

I can not even check right now, because I can not open the page at all and I don't rememember exactly which blocks I was using there. So I should get back to PHP 7.4 to access the page.

But even when I will be able to see which blocks I have there, how can I find out which is the block causing the problem?

Thanks!

1. Check your PHP error log.
2. Take a look at the blocks in the ACP to see if any contains any customized templates. If yes, review them and make sure that the used code works with PHP 8 / PHP 8.1

In the "Systems Log" I get thousands of this:

And if I open one I get this:

any customized templates.

Well yes, I have cusotmized templates. But how can I find out what is not working? And why PHP 8.0 give all these problems?

1 hour ago, Marc Stridgen said:

Well, that would depend on the ability of yourself as a developer really

I also have another problem with PHP 8.0. One of my pages does not work with PHP 8.0, while it works if I get back to PHP 7.4. That page is made up only by IPS blocks, nothing else. What can I do to solve this? Thanks!

It may be its not updated for PHP 8

Is it possible for me or someone else update it for PHP 8? Or only the plugin author can do it? The user is not connecting here for more than one year so it would be useless to contact him. Thanks!

I have found out what was causing the problem: this plugin which is not updated for version 4.7: https://invisioncommunity.com/files/file/7853-online-indicator/

Maybe I should change some of these settings when I change to PHP version 8.0?

I had to go back to PHP 7.4

The problem caused by PHP 8.0 is the following

PHP Fatal error: Cannot use "parent" when current class scope has no parent in /var/www/vhosts/totallympics.com/httpdocs/system/Theme/Theme.php(2703) : eval()'d code on line 39

Any idea how can I solve this?

I have updated PHP version to 8.0, cleared the cache, and now I can not access the website at all:

There is not here, as the stack trace is rather generalized. Unless you are aware of if there are any which hooks into this:

marktopic_hook_code_forums_modules_front_topic

Update: Actually yesterday the problem was fixed by itself 30-45 minutes after the downgrade to PHP 7.4. The problem was still happening after the downgrade, but then some minutes later it was fixed by itself. I didn't do anything and my hosting service also didn't do anything. Is that possible? And is it possible that would happen also if I keep PHP 8.0?

You can change back to 7.xxx and get the access back-simplest way 

Yes, but I have to understand what cause the problem, otherwise it will surely happen again in the future when PHP 7.4 will not be supported anymore!

I guess this "marktopic" is from this plugin:

The user is not connecting here since April, so I guess there is no way for me to contact him.

I tag the three users who wrote a review for this plugin. Did you face any problem in upgrading to PHP 8.0 with this plugin enabled? @Edjazoli ; @BankFodder ; @Grafidea

Thanks!

As Daniel mentioned, there is a custom theme or third party application/plugin which is causing this issue. You would need to find out which one it is and then disable it and contact the author. 

But isn't there any way to find out which custom theme or third party application/plugin is causing the issue? Disabling them one by one can be very time consuming, considering when I update the 8.0 I can not even access the adminCP. Thanks!

Alternatively, you will want to go back to PHP 7.4

The problem is now fixed with PHP 7.4

But I want to use PHP 8.0 going on.

Any idea what could cause the problem?

Thanks!
 

So to make a summary:

-This morning I had IPS 4.6.12.1 and PHP 7.4, everything was working fine.

-I have enabled PHP 8.0, and the theme problem happened

-I have enabled PHP 7.4 again, went in AdminCP, cleared the cache, and everything was working fine

-One hour ago I have updated to IPS 4.7.1, everything was working fine

-I have tried to enable PHP 8.0, and the theme problem happened

-I have enabled PHP 7.4 again, but now I can not go to AdminCP so I can not clear the cache and solve the problem

Any idea how can I enter the AdminCP now?

Thanks!

If I just could enter my AdminCP, I would clear the cache and the problem would be fixed (since I am now running again PHP 7.4). It happened the same when I tried to do so with IPS 4.6.12. But right now I can't enter the AdminCP so I can not clear the cache!

Just now, Daniel F said:

That’s a problem with a 3rd party application or plugin with a theme hook. Try disabling one by one too see which causes this.

I currently can not even open the AdminCP!

Hello,

I have recently updated my version to IPS 4.7.1, and then asked my provider to update the PHP version to 8.0 (from 7.4).

Just like it happened when I tried to update to PHP 8.0 before (but I thought it was I still had IPS 4.6 version), here is the problem I face:

Also, I can not access my AdminCP. When I click on mywebsite/admin, sometimes I get a blank page, sometimes I get this error message:

Any idea why this happens?

The provider sent me the error message (related to my theme):

PHP Fatal error: Cannot use "parent" when current class scope has no parent in /var/www/vhosts/totallympics.com/httpdocs/system/Theme/Theme.php(2703) : eval()'d code on line 39

Thanks!

The only way to do so would be to switch to it then run the requirement checker. You can of course ensure your server is running the minimum requirements for PHP 8 before switching it, and check with the authors of any 3rd party items before doing so

Hello,

is it normal if I upgrade to PHP 8.0 before with the IPS 4.6.12.1 version, everything gets messy? Like my whole theme got broken and I had to put PHP 7.4 version again.

When I will update to IPS 4.7.1, I can switch to PHP 8.0 and that will not happen?

Thanks!

Hello Jim,

what is exactly the "core CSS"? I mean, where could I find that in 4.6 version? Thanks!

Code would be difficult because you can’t control formatting. Things like spaces, tabs, etc all make parsing code almost impossible to do accurately. <b> This is a test </b> is different than <b>This is a test</b>

Yeah, but I would need only the text start with <b> This to be automatically changed into <b>This

This is not possible to realize?
