I logged in as admin. I opened the css configuration page. I clicked edit rules page. After that, css edit rules page should open but my site is stuck at screen 2(home page). After I click edit rules many times, sometimes, I get the edit rules page. I feel that this is a site wide issue not css injector issue.
Example: If I click Save on views page, it does save but my page gets stuck at the home page. I have to hit the back button to come back to view and I see that views is already saved.
If I click clear cache in performance page, I have similar issue. It does clear the cache but the site is stuck at home page. I hit back button to come back to performance page again.
I simply do not know where to start troubleshooting. I am not getting any error messages. If you could point me to right direction to solve this issue, it would be very helpful.
