    Deactivated some plugins, and after that, on the posts and pages create menus I see next error message on the top of monitor “”Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, ” was given in /home/content/39/8986139/html/a-t/wp-includes/plugin.php on line 505″”

    Can you PLEASE help me by advice what to do?
    Also, facebook debugger can’t see featured image anymore, it shows me tons of other picture and just site layout instead of picture on preview box….

    T H X!!!

    Hi Deadcenter,

    Can you check if everything on your WordPress is up to date?
    If not, take a full backup and then update it all. Does this change anything?

    In any case this is a warning message and not super serious. Is your WordPress site in debug mode? I have a quick tutorial on how to do this here: https://conschneider.de/how-to-enable-wordpress-debug-mode/ – try installing the plugin mentioned and check whether checkbox number 3 is activated (the one saying: checkbox 3 – “Enable Display Errors”) – if yes then unchecking and saving it should get rid of the warning.
