 * I keep getting 503 Service unavailable error, I contacted Namecheap regarding
   the issue. The agent stated that some plugins are using most of the resources.
   He didn’t tell me which one. How to know which plugin is using the resources 
   that I’ll uninstall it and find an alternative.
   I have tried various means but
   still can’t resolved the issue

 * One approach is to use a process of elimination, disable all plugins and then
   activate one by one, but that is assuming you have a tool to measure.

 * Hi [@alanfuller](https://wordpress.org/support/users/alanfuller/) 
   Thank you 
   for your assistance.I had to use the process of elimination, disabling the plugins
   one after the other, turns out the litespeed cache plugin I installed was the
   issue.It has been rectified, thank you for your assistance.
