Please try this version - it resolved the PHP 8.x issue and will be the basis of a new release tomorrow.

Does not work here with PHP 8.1. Error

0 version_compare(): Argument #3 ($operator) must be a valid comparison operator

With PHP 7.4 it's ok.

Can you enable Joomla debug mode so I can see where the error is being called? I had found one potential problem area but it looks as though there may be another

I have got same error on PHP 8.1. Using Jevents 3.6.42.
When going back to jevents 3.6.39 I can edit and make new events without error and still using PHP 8.1.

Just installed jevents 3.6.43dev and got this error:
Hope it can help :-)

An error has occurred.

I was trying to make a new event, when I got the error.

I'm really embarrassed to say that the package I uploaded yesterday was built BEFORE I'd fixed the problem - more haste less speed . This version definitely resolves the issue at this point

Thanks, upgrade on JEvents is working for me. (Joomla 3.10.11)

Also thumbs up from me. It is working with PHP 8.1 and Joomla 3.10.11.
Thank You :-)

Not a thumbs up from me. I am currently running Joomla version, 3.10.11 and running JEvents v3.6.43rc1. Any help will be appreciated.

Thank you

The package published yesterday works fine with Joomla 4.2.3 and PHP.

Thank you very much and kind regards

Not a thumbs up from me. I am currently running Joomla version, 3.10.11 and running JEvents v3.6.43rc1. Any help will be appreciated.

Can you enable Joomla debug mode and give me a screenshot of the errors you get please so we can see what file and line number is causing the problem.
