Describe the bug
A fatal error occurs if, in OJS 3.3.0 (tested on build 15), the Web Cache setting is active under PHP 8 (8.0, 8.1, 8.2). This doesn't happen if I use PHP 7.4.

To Reproduce
Steps to reproduce the behavior:

1. PHP 8
2. web_cache is On (config.inc.php)
3. Visit site

What application are you using?
OJS 3.3.0-15

Hi @kswro! The short answer is that the web_cache is known to be broken and should not be used. We have some discussion/early work on a better caching toolkit on #7111; I'll leave this issue open in the meantime in case anyone cares to work on it. (But I don't recommend it.)
