Support Ahmed and how you did that?
well i’ve changed my cache plugin to Quick Cache
It’s really easy to configure and save’s me between 1 and 2 secounds more than W3 Total cache on page load and dont have any issue with UserPro..
I’m having a similar issue, if i try to login using email and password it doesnt work.
It works using social networks but after the login or I go to the back-end area or I get logged out if ~I try to navigate on the site :/
