Hi,
Which version(free or pro) are you using?
The plugin is already compatible with PHP 8.x.
Please login in your cPanel, attached the error log screenshot so that we can understand the issue.
It’s version 5.8, free version.
The error message is this:

And if I deactivate the plugin, the website works again normal.
Thank you.
I deactivated the plugin W3 Total Cache and now it works.
