Does anyone know why admin-ajax.php is taking over 3 seconds of the loading time on this page i am trying to optimize?
It have something to do with a CSS file, but why does admin-ajax.php GET the CSS file?
I am really clueless.
For two whole working days i have been trying to find a solution for this but i really cannot solve the problem.
I hope someone can help.
The Theme was very old, and support told me that the bug had been fixed in a newer version of the Theme. They were aware of the bug, and the only fix was to upgrade or dive deep into the themes coding and fix it yourself.
