• We encountered an error when we try to navigate the menus Header and Background of wordpress dashboard. Here is the specific error displaying on the browser:

    Fatal error: Call to a member function set_return_url() on a non-object in /home/mxxx/public_html/wp-admin/customize.php on line 28

    We are using the theme Twenty Sixteen. We tried disabling and deleting all plugins, no content for .htaccess, updated wordpress to its current verions but none of these works. There are no problems with other websites, just 2 websites. Does this have anything to do with the hosting security at cpanel?

    Please help!

    Have you tried:
    – deactivating ALL (yes all) plugins temporarily to see if this resolves the problem (plugin functions can interfere). If this works, re-activate them individually (one-by-one) to find the problematic plugin(s).
    – If you can’t get into your admin dashboard, try resetting the plugins folder by FTP. Sometimes, an apparently inactive plugin can still cause problems. Also remember to deactivate any plugins in the mu-plugins folder (if you have created such folder). The easiest way is to rename that folder to mu-plugins-old.
    – switching to the unedited default Theme (Twenty Sixteen, etc.) for a moment using the WP dashboard to rule out any theme-specific issue (theme functions can interfere like plugins). If you don’t have access to your admin area, use FTP , or your web-host’s cPanel or whatever file management application your host provides (no Dashboard access required). Navigate to /wp-content/themes/ and switch to the default theme by renaming your current theme’s folder by adding “-old” to the end of the folder name. Alternately, you can remove other themes except the default theme. That will force your site to use it.
    – If all the above steps do not resolve the issue, then try MANUALLY updating. Download a fresh copy of the WordPress .zip file to your computer, unzip it, and use that to copy up all files and folders EXCEPT the wp-config.php file and the /wp-content/ directory. You may need to delete the old wp-admin and wp-includes folders and files on your server before uploading the new ones. Please read the Manual Update directions first.
    Backup: If you haven’t already done, always backup everything (including your database) before doing any actions, just in case something really goes wrong.

    hello there,
    Did you check your site on all browsers. sometime cookies issue can cause this problem. Please check your site on other browsers too. If this does’t solve your issue you can try a fresh install of wordpress to your server as suggested by Tara.
    Thanks
