Support » Fixing WordPress » Fatal errror when clicking on media or trying to upload

  • I have uploaded a site from my local host to a subdomain so the client can view. http://safehorse.toplinemediateam.com/
    When in wp-admin, I click on Media and get this error.
    Fatal error: Call to undefined function mb_detect_order() in /home/toplinemediateam/public_html/safehorse/wp-includes/functions.php on line 2769

    I also get this error when trying to create a new page or post.
    Fatal error: Call to undefined function mb_detect_order() in /home/toplinemediateam/public_html/safehorse/wp-includes/functions.php on line 2769

    Deactivating the theme and using 2014 solves the issue, but I need that theme. It was working fine on localhost.
    Suggestions?

  • If the problem resolves when switching to another theme, the problem is most likely something in your theme. Just to confirm, you can de-activate the plugins and re-activate one by one as well to see if it’s a combination of your theme and a specific plugin.

    You’ll know it’s the theme as well if the same set of plugins work fine for Twenty-fourteen but not with your theme.

    Does your local copy and subdomain match exactly as far as theme changes and plugins go? This includes the versions?
