Hi @robhob and @nisha,
Hope you are doing well. I deactivated the plugins one by one. I found that the problem was with Insert Headers and Footers plugin. Now it’s resolved.
I need a suggestion. Most of the forums point out the same problem to be because of Photon, Jetpack. So, as my problem wasn’t due to it, Should i use photon and activate it?
Thank you very much.
