Fatal Error on install

  • cmiale


    I tried to change the Graphene theme on a blog rippedusa.com/blog and I got this fatal error on all pages. Including the sign in page /wp-admin. I cannot get back in or see any pages. Only this:

    Fatal error: Class ‘Walker_Nav_Menu’ not found in /home/ripped01/public_html/blog/wp-content/themes/graphene/functions.php on line 674

    Any ideas on how to fix?

    It could possibly be a plugin conflict. Are you using any sort of plugin to modify the menus?

    If not, try using FTP to upload a fresh copy of the functions files.

    Which version of WordPress are you using? If it’s a very old version before the Custom menu feature was introduced, that might explain it.



    I didn’t modify anything. I literally went to WordPress found the theme, clicked install and got the error messages.

    Where would I get the functions files? How would I upload them if I can’t get into WP at all? And where do I want to put them? Sorry…a little above my skill level.



    It probably is an older version. The owner hasn’t used the blog since 2010, and I am going to update it for him.



    It sounds like what I really need is WordPress support.



    What you can do is FTP to your website, and rename the graphene directory, to something like graphene-renamed.

    Then, you should be able to log into your admin panel, using the old theme, and perform your updates.

    Once you are done, you can go back and change the name of the directory to graphene. And test it again to see if it works properly.

    Do you know how to create an FTP account through your hosting provider?
