Blank Screen in WP Admin Dashboard

Howdy, Y’all,

I had two subdirectory sites that showed a blank screen no matter what links I clicked in admin. I deleted one of those sites because I don’t want it anymore, but the other is giving me the same errors. The errors after setting debug to true in wpconfig were the same if I remember right. They are completely different in the error logs in the subdirectory folders.

Error in admin panel is:

Notice: has_cap was called with an argument that is deprecated since version 2.0! Usage of user levels by plugins and themes is deprecated. Use roles and capabilities instead. in …(subdirectory)/wp-includes/functions.php on line 3551

Error for the still existing site in the error log is:

PHP Notice: Undefined variable: post_class in …/wp-content/themes/chip-zero/chip/common/page-content.php on line 10

In the phpMyAdmin wp-options table I changed these three fields back to ‘twentyeleven’

template (on page 2 with 30 records per page)
stylesheet (on page 2 with 30 records per page)
current_theme (on page 4 with 30 records per page)

Problem still persists, though I didn’t disable debug in wpconfig.

Site works fine. WP admin does not.

The site that I killed had a lot of plugin errors. This one does not. Supposedly it’s theme related according to the error log but, like I said above, changing themes seemed to make no difference. I even gave it a few minutes for the changes to kick in. Still the White Screen of Death with the same error.

By the way, this one uses the Chip Zero theme which was abandoned a long time ago.

I just wanted to delete links pointing at the recently deceased subdirectory site.

Thanks,

Me
