    Hi,

    Heres a image of the error:

    After re-installing wordpress the error is gone for a few hours but then it comes back. I am very helpless since i dont know what to do and its a live site and my customer can not use the page anymore. Anyone any idea?

    Thanks in advance,
    Andi

    You should check if the file wp-includes/media.php is modified by some code within your website. Usually malware modifies the WP core files, so you should scan your WordPress instance for malware.

    Hey @rosehosting,
    You should consider clearing your cache and cookies and check if the issue still exists.
