Hello,

After upgrading to PHP8 my pros site is no longer available,

Please help

It's possible that the theme does not support php8.0, or there's a missing component

An error occurred (500 Error)

We're sorry, but a temporary technical error has occurred which means we cannot display this site right now.

Please check your server's PHP or web server error logs and paste what is being logged there.

If you don't know how to access this information, you will need to contact your hosting provider.

What version of Invasion Community Suite?

What version of PHP?

Before the production server upgrade: Invision Community v4.7.1 with PHP Version 7.4.3-4ubuntu2.19.

After: Invision Community v4.7.1 with PHP Version 8.0.29

Yes, switch php back to v7 and see if site works again which it should.

You may have some customisation that is incompatible with php v8.

Try disabling all applications and plugins, switch to default theme and language then tryphp v8 again.

Looks like 2 issues (at least) with 3rd party applications (or plugins). There's no way to tell which one from the error log, so you'll need to disable all of them. Once you do that, you can check the PHP scanner in the support section of the ACP to see which modifications have been flagged.

That said... the second error message in your logs won't be flagged by the scanner. That one is going to have to be trial and error to figure out which is the culprit. 

But the PHP scanner doesn't exist in Invision Community v4.7.1, why i have compatibility issues?

Your tech support here said that the best practice is to upgrade the server first to avoid this scenario.

Edited August 6, 20231 yr by LiveG

Misread it as 4.7.11. Sorry about that. 

In that case it's trial and error. Disable everything, then enable one by one until you check them all. Likely more than one with an issue. 

i don't have admin access, everything is down.

As stated here, you'll need to switch back to PHP7, then disable everything, and then switch back to PHP8.

Alternatively, you can roll back to PHP7 and then reach out to the author(s) of your modifications to verify PHP8 compatibility. 

Let's say I roll back to php7, disable every app, and the upgrade to PHP8 will be successful,

when i am will start to enable them one by one, everything will crash again in some point, and if there is more then one?  sound like an inefficient way to handle this case

That's correct. I would suggest reaching out to the authors of the modifications to verify that their applications/plugins are compatible.

Can you check the installed App's/plugin 's page here at the Marketplace to see if any of them is not compatible with php 8? That might save you some time. You should look especially into the apps/plugins that have to do with topics, as the error messages you posted above indicate that

 

Update: I rolled back to PHP 7 and everything working again.

Well, I have a lot of apps. some of them are custom and critical apps. It will be a very painful procedure to understand what is the source of the problem.

Is there any way to prevent the forum from totally crashing when upgrading the server to PHP8 and enabling apps one by one?

Maybe i should set up a test env for it.

I don't think there is, if you don't know the culprit.

You should start with the custom apps that affect the topics, as mentioned above. Most likely one of them is going to be the culprit as most apps here at the MP from what I have seen are php 8 compatible.

That is a good idea. Like that you can identify the culprit without disrupting your main forum. The thing with this is that if you can' upgrade your php to affect only the test site, you will have to disable all third party plugins/apps for your main site till you find the issue. 

If you want a quick and easy way of figuring it out...

You're self-hosted so therefore can use FTP.

1. Download the /applications/appname and the /plugins folder to your PC (appname = the names of the non-IPS folders for applications you have installed)
2. Using a text editor such as Notepad++, do a "Find in files"
3. Use getItemsWithPermission as your search term
4. Search away

There ya go - found one, contact the author after ensuring you are already running the latest version of that resource.

Hi,

Thank you, i will try it!

I am afraid i don't have /applications/appname folder - is it normal?

Edited August 6, 20231 yr by LiveG

It's perfectly normal - I doubt anyone has named their application "appname", and I wrongly assumed that the following hint was enough:

Quote

appname = the names of the non-IPS folders for applications you have installed

Look at the folders under /applications....they are the folders for the applications you have installed, figure out the non-IPS ones (which are forums/blog/cms/core/nexus/commerce/downloads/calendar/convert/gallery)

I found the following,

I will contact the authors, thanks a lot!!! @Nathan Explosion

Calendar is an IPS application. If it is up to date, you're fine as it is compatible with PHP 8.

I told you to ignore the Invision applications by indicating 'non-IPS'

Edited August 6, 20231 yr by Nathan Explosion

HI,

I disabled all of the apps, moved to the default theme, and then upgraded the server again to PHP8.

After the upgrade, the ACP problem indication was gone.

Now i have admin access, but my site is down (BLANK SCREEN); please advise?

I have tried to upgrade to the latest software version and all of my forums crashed. even the admin ACP.

I need official support from IPB. Is it possible to login remotely?
