PHP 8 is pretty cutting edge and I would suggest waiting a couple more months before using it on a live site.

If you enable Joomla debug mode and error reporting to maximum what error information do you get?

there were many errors that could be related to jevents
i switched allready back to 7.3 because the site wouldn't work anymore with php8

Hello,
i also testing my website with PHP 8.
Had some templateproblems, but i fixed it.

JEvents 3.6.12 works with PHP 8,
but i get some deprecated-messages:

But i can wait for the fix.
Just testing

These are all deprecation messages - for a live server you should set the error reporting to none in the Joomla config. I'll review the messages for the next release but these are not fatal errors so far

Note, Joomla! isn't actually fully compatible with PHP8 yet so it's highly not advised!

Thank you.
I just testing my website with php8.

But it has time. No problem!

Hello Everyone !
Do we have an update on that subject?
I have been having the exact same issue for a while and I have no choice but to shift top php 8.0.(managed to fix all my other joomla issues)

Is there a mean to bypass the problem in the meantime?

Thanks a lot
have a nice day

My J3.10.8 site works perfectly in PHP 7.4.3, but when I switch to 8.0.18, I get this error on the calendar web page:

count(): Argument #1 ($value) must be of type Countable|array, int given

And a 500 error in the log. When I unpublish the JEvents - Latest Events Module (3.6.34,April 2022), the page loads fine (minus the calendar, of course).

After troubleshooting this further, it appears that except for the first option (Date, Time, Title), all of the predefined custom layouts in the JEvents - Latest Events Module 3.6.34 cause a 500 error in PHP8, with this error in the browser window:
count(): Argument #1 ($value) must be of type Countable|array, int given

All custom layout options in this module work as expected in PHP 7.4.

Can you enable Joomla debut mode so we get the full context of the error? Or give us login details on the private site details tab below

Debug mode is now on.

Thank you in advance for your help!

What version of the JEvents Structured Images and Files plugin do you have installed?

Your line numbers don't match the latest codebase. I suspect you need to upgrade this plugin.

I don't see a plugin by that name. I have JEvents - File and Image uploads for Event Descriptions 3.7.14. Do I just need to upgrade that?

The latest version of the plugin is version 3.10.6 - I suspect upgrading it will resolve your issue
