Visual Composer - Backend Editor Error
If Visual Composer won't load in the back end when you try to edit some page, please first make sure that you are using latest theme version with latest Visual Composer. Please follow update instructions or video guide:
If this is not the case and you have following problems when accessing site or editing pages:
- Failed to load resource: net::ERR_CONTENT_DECODING_FAILED
- customlibEditGallery java script error in the console when you open developer tools in Google Chrome
- not found 404 page is displayed when editing pages
- Uncaught TypeError: $(...).wpColorPicker is not a function
which was confirmed several times with GoDaddy hosting plans and also with few SiteGround hosting users, and problem is hosting related and it is due to mod_security check when some robust and feature rich themes from Theme Forest is used:
SOLUTION IS SIMPLE:
Add following module to WordPress .htaccess file:
...after the # END WordPress:
...and try editing pages. If the problem persists, replace that line of code with the following code:
#WPBakery Timeout fixer - .htaccess
...as seen here:
After that try to edit pages again.
Everything should be working fine after this change.
