I am having a wordpress site .I have Changed my site url in phpmyadmin from example.com to www.example.com . But i noticed everything else is working but the pages created using Visual Composer plugin are not opening and pages are only opening in Classic Mode of Editing and No option to open page in Backend Editor or Frontend editor
There is one weird thing I mentioned that when i have changed website url from example.com to www.example.com only then this problem occurs
But when I again rollback it from www.example.com to example.com then visual composer works fine . Is there any other place where i need to make changes
Without going into a rabbit hole, this issue is caused by the length of your URL.
Adding a line to the .htaccess file should solve your issue, as Visual Composer (now WPBakery) can’t cope with URLs longer than a certain length.
