[osTicket] How to get rid of error 500 in IIS 7.5?

Question

PHP

Good day!
Given:

1. web server on Windows 7 x64
   
2. Microsoft-IIS/7.5
   
3. MySQL Version 5.7.21
   
4. PHP Version 7.3.7
   
5. APCu
   
6. Zend Opcache
   

1. Periodically, usually at the first visit to the site, images on the site are not loaded. If you refresh the page, then all images are loaded correctly.
2. Periodically, when performing any operations on the site, the Error "HTTP 500 - Internal Server Error" occurs. Moreover, on older PCs with low performance, this error occurs much more often.
An error can also occur if the images did not load and the refresh button was pressed several times quickly.

Please tell me, what is the reason for this behavior of the web server and how can these problems be solved?

Answer 1

you need to open the server logs and carefully read what kind of internal error this is.
