Hey,
I started having very strange problems with the system, happening all over the site including the admin panel
For example
When I click on the Contact Us button in the forum, the window opens properly, but when I want to close it by clicking on the X button, it simply does not respond - the solution is just to refresh the page
In addition, in the admin panel, when I enter the forums menu and want to see all the forums in the category, it shows me the window like this
Another problem in the admin panel is when I click on System menu > Advanced Configuration and then wants to enter one of the tabs, he thinks and moves around non-stop (when I click open in a new window on one of the tabs, it opens normally) - this happens in part of the admin panel and not in all of it
The server ran a version of PHP 8.1
This is a clean and new installation of the forum system a few days ago
The problem started a day or two ago
what can be done ?
