I have 3 question

Have you tried disabling all non-GP premium plugins?

No, I am afraid because I can not find out the exact problem.

But that's the steps you need to take to locate the problem.

I assume the problem will disappear once all non-GP premium plugins are disabled, then you can re-activate them one by one to pin down the problem.

I tried but can not find the problem. please help me.

If you permit me I will send my admin login details via

Or If you have any other way to share login details.

Please help me.

This is something you will have to do by yourself. I still see other plugins activated on that page.

We can take a look at the page once you disable all plugins (except GP + Code Snippet where you added the author photo snippet)

I deactivate most of plugins. please check now.

Currently, only activate thrive architect because when I deactivate this content disappear. and GP premium also activated.

Finally, I find the culprit plugin which is jetpack. Now I turn off this popup gravatar settings.

Please check now. And send me CSS code.

Now I solve the problem.

Solved problem, thank you

No problem!
