    Hi all, hoping the wizards of WordPress and php can help me solve these two php errors that just appeared.

    Our site was migrated to a new server, it was working just fine before. A hosting company moved it for us. Suddenly these errors appeared and I want to understand what happened and how to fix it. A ***xo

    I removed the url name for abuse issues. Heres the url to see the site live: https://tinyurl.com/zwfyjp9

    Here are the errors:


    Error one: is the on the site after you go in further.

    Warning: Invalid argument supplied for foreach() in /home/___________/public_html/wp-content/plugins/display-opencart-category/wpdocc_main.php on line 33

    Error two: On the login page:

    Warning: Cannot modify header information – headers already sent by (output started at /home/_______________/public_html/wp-content/themes/twentytwelve-child/functions.php:28) in /home/_______________/public_html/wp-login.php on line 394

    Warning: Cannot modify header information – headers already sent by (output started at /home/_______________/public_html/wp-content/themes/twentytwelve-child/functions.php:28) in /home/_______________/public_html/wp-login.php on line 407

    Update: The display-opencart-category was solved by renaming that plugin, but the other login page still is there. A xo

    In the Headers already sent error, you see this line
    /themes/twentytwelve-child/functions.php:28

    It is outputting something on some WP hook which is executed way earlier on the page generation stage which creates this headers already sent error.

    You may look into that code , or add that code in this thread so we can see what it is trying to do, could be some WP function which might needed new parameters or something…
