I managed to speak with a website developer on Fiverr who claimed he could fix this. He is charging $60 for his service.
I need some advice from you guys, my renewal with Hostgator is due next month. Is it better that I switch Hosting provider, or hire this Fiverr guy? Will switching Host solve this issue? I was thinking if I'm going to switch host then what's the point paying $60 to this Fiverr guy? Might as well pay for a new hosting provider but I'm not sure with my current wp-admin still blocked by ModSecurity, will switching host at this stage possible?
Your advice much appreciated.
