Call To Undefined Function Metadata_Exists After WordPress Upgrade

IT Problem

As fellow wordpress users know, the latest version of wordpress, version 3.3 was released this week. So as per usual I set it away to upgrade automatically. After about 5 seconds it came back with this error.

Fatal error: require() [function.require]: Failed opening required ‘/home/yourfolder/public_html/wp-includes/class-wp-editor.php’ (include_path=’.:/usr/lib/php:/usr/local/lib/php:/home/allenwhi/php’) in /home/myfoldername/public_html/wp-includes/general-template.php on line 1808

OK, I thought, lets just check the site is fine. So off I went to check my site, then i got this..

Call to undefined function metadata_exists() in /home/myfolder/public_html/wp-includes/capabilities.php on line 552

EEEEEKKKK!.

Turns out a security plug-in had set my \wp-includes\ folder to read only.

IT Solution

So to fix the issue I did the following. In dreamweaver I went into remote view ( YOU MUST DO THIS )..

dreamweaver remote view

dreamweaver remote view

I then right click over the wp-includes folder and went to Set Permissions.

 

set file permission in dreamweaver

set file permission in dreamweaver

 

Then finally I set the folders permission to 755 which allow only the administrator to “write” changes.

 

set wp-includes to 755 permission

set wp-includes to 755 permission

Ok so now I was back in the situation where I can upgrade my word press install. The next problem was that I could not do it automatically. So I then had to upgrade it manually. Read on..

Upgrade WordPress Manually

So first I downloaded wordpress 3.3 from here

I then extracted it to a temporary folder..

Then I took a FULL BACKUP of my website locally.

Then you need to copy the folders all files & folders – except the wp-content folder from a the download of WordPress. Again I repeat DO NOT UPLOAD THE FRESH WP-CONTENT.

Once all the files have uploaded you will need to go the URL below, replacing your site.

http://yoursite.com/wordpress/wp-admin/upgrade.php

You should then be able to upgrade successfully. Make sure you again now take a full backup of your site.
