3.3 Upgrade Now site Broken

Here are lines 2101 to 2104 from the general-template.php file if this helps:

echo apply_filters( ‘wp_admin_css’, “<link rel=’stylesheet’ href='” . esc_url( wp_admin_css_uri( $file ) ) . “‘ type=’text/css’ />\n”, $file );
if ( is_rtl() )
echo apply_filters( ‘wp_admin_css’, “<link rel=’stylesheet’ href='” . esc_url( wp_admin_css_uri( “$file-rtl” ) ) . “‘ type=’text/css’ />\n”, “$file-rtl” );
}

De-activate the “pop up domination” plugin if you have it activated:

Update:

I got the site working again by renaming my plugins folder to plugins.old

But will renaming it again work?

what should my steps be now to fixing this issue?

Make sure you’ve read the entire Master List post and the New Features in 3.3 Post.

Go to your own install’s about page – https://domain.com/wp-admin/about.php – to see what’s new.

And then make sure you’ve tried…

– flushing any caching plugins you might be running, as well as server and/or browser caches.

– deactivating all plugins (yes, all) to see if this resolves the problem. If this works, re-activate the plugins one by one until you find the problematic plugin(s). If you can’t get into your admin dashboard, try resetting the plugins folder by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause problems. Also remember to deactivate any plugins in the mu-plugins folder. The easiest way is to rename that folder to mu-plugins-old

– switching to the Twenty Eleven theme to rule out any theme-specific problems. If you can’t log in to change themes, you can remove the theme folders via FTP so the only one is twentyeleven. That will force your site to use it.

– manually upgrading. When all else fails, download a fresh copy of the latest.zip file of 3.3 (top right on this page) to your computer, and use that to copy up. You may need to delete the wp-admin and wp-includes folders on your server. Read the Manual Update directions first!

Ive went further and renamed my plugins folder from plugins.old to plugins once again and after looking around renamed my popupdomination folder from that to popupdomination.old and the site is still loading so I am assuming like others its from this plugin.

This plugin I really love so what are the steps from here to get this plugin working again without affecting the site loading?

Would appreciate it!
