Hello,

Can we get access to that please? We don't natively support PHP 8 yet as we are still implementing some fixes.

Many thanks
Tony

Tony,

What do you want access to? I'm running this setup locally within Docker on Debian 9.

Ahh ok, can enable debug and also max error reporting and provide a snapshot of the error so I can isolate it. With the exact steps to recreate it?

I'm not seeing anything in the apache logs that's showing the error. I also enabled display errors, but that had no effect on the message Joomla is showing:

"An error has occurred.
0 Path cannot be empty"

I additionally turned on debug mode in my apache settings, but it just output that it was granting access to the URLs requested. It seems like the ManageEvents is looking for icalevent.list, but I'm not seeing that method unless it's in a parent class.

I enabled debug mode in Joomla and this is the stack output

when you look at your debug results the specific files at those specific positions there are some values or variables that has it's values as string rather than an array. e.g. '' or "" should be surrounded by [] to give [''] or [""] or just [] but currently there is an awful lot to be fixed to work with PHP 8.0. Actually a lot of Joomla components have this problem. For the time being, I'm still using PHP 7.4 to solve the problem for now. I really hope jevents can fix compatibility with PHP 8 soon. Thanks jevents for a great product.

Hello,

No problem! We actually fixed a core issue in the Joomla! Cache recently to the Joomla! Core. Let's see if it's still there in the next release of Joomla!

Many thanks
Tony
