I understood the decision woes. Firewall has blocked all Singaporean ip. Your server is located on the IP 128.199.194.176. I added this IP into permitted and everything was working fine. What else do you use an IP address?
Thank you. Your advice helped. The speed of the Admin Console recovered. Plug-in diagnostics only gives error between HydeMyWP and AJAX. What steps need to do to find out where the error occurs?
