Hey Mohammed, thanks for the reply.
My site is hosted on WPEngine with shared hosting and this site of ours is using resources excessively so we got an email from WPEngine itself to take care of this before they suspend our site.
They sent a log of certain “action” and a list of plugins to which those actions belongs.
I have added such ticket to all of them.
I am not allowed to share that report here else would do that. I guess this information will help you to suggest some steps to resolve this issue.
Thank you in advance.
