 * Hi
 * I bought a shared hosting from namecheap and installed wordpress. I have not 
   made any settings except the main WordPress settings (such as Permalink) and 
   I have not installed any plugins (such as firewall, etc.) My host webserver is
   also LiteSpeed.
 * The LiteSpeed cache plugin is the first plugin I installed, but when I make any
   changes in the Page Optimization section, I encounter this error:
 * > 403 Forbidden
   > Access to this resource on the server is denied!
 * I checked all the permissions in my host’s file manager. All permissions were
   correct. But I don’t know why this problem occurs!
   There is also an interesting
   point. When I do something through the Presets section and apply a preset, it
   is applied correctly and the settings in the Page Optimization section are also
   changed!This problem has been driving me crazy for three days.please guide me.
   Best regards

 * this is most likely due to mod_security , please check with your provider on 
   this part , the server log will indicate the reason
