  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

Issue Error 500 PHP

S

New Pleskian
Hi
We have servers the following configurations :

Windows Server 2019
SQL 2019
PHP 7.4.33
Memory : 80 GB
CPU : 16 Core
Plesk Version : 18.0.58

We designed the site with php and Sql.Recently, the site is facing many 500 errors.
Nothing can be seen in the error_log other than normal php warining.
By refreshing the page, the site opens quickly.
The number of users increases, the site slows down, and after displaying the 500 error again, the site speed is good!

Please guide me how can I troubleshoot.
 
See attached file plz
