The users during the enter to one of the sub-forums and instead of the list of the topics receive the error:
Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 20480 bytes) in /home/master/site/system/Db/Select.php on line 503
(Invision Community v4.7.5. Running latest version. 0 critical issues and 0 recommendations. PHP 8.0.20. 10.5.16-MariaDB.)
This error appears in the browser Edge (sometimes in Chrome). In other browsers (Opera, Firefox) I haven't noticed this error.
I fully cleared the browser caches, cleared the forum caches, disabled the customization in the browser and in Admin panel of the forum, switched the forum to the standard skin. I've checked up database on errors. But the error on forum didn't disappear.
But InPrivate mode of the browser functions ok. The guests don't receive this error and look the sub-forum without problems.
In file php.ini I've changed memory_limit with the value 128M to the value 512M and the sub-forum began to function. I've stayed 512M as a temporal decision.
Please, help to dispose of the memory leak.
