Fatal Error on WP>Appearance >Nav-Menu

[majidkazmi]

I got an email from WP saying there is a fatal error on my site. The error is detected on the page http://ugen.ca/wp-admin/nav-menus.php. The website host suspects that the problem is related to the website scripts compatibility issues. The Menu on the Appearance tab on WP does not open properly. Is there a solution?

Here are the error details:

Hi @majidkazmi,

Thanks for writing to us.

This happens when you update with FTP by replacing the original files. Many files were moved in this update, but FTP doesn’t account for this and leaves the originals. Things end up polluted as you have multiple copies of the same file in different places. This leads to fatal PHP errors about functions or classes trying to be re-declared.

Whenever you update with FTP, be sure to fully delete the original or at least rename it so only the new files exist in the final location.

Thanks
