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:

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?

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!

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

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!

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 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!
