I'm not 100% sure, but I seem to be having caching issues with php scripts. When I change the scripts non dynamic content, and shift + F5, it doesn't seem to change right away, it takes a few minutes. could this be caused by a server setting? I added Code: ini_set('opcache.enable', '0'); to my script and it no longer seem to have the issue. Is there any way to disable opcache for a single domain?
