I know there are threads about this problem already, I apologise for the multiple posting, but I have a broken blog and I really would like to move forwards somehow.
When uploading images and when saving new pages, this error occurs
Fatal error: Cannot use object of type WP_Error as array in /home/kudelka/public_html/wp-includes/taxonomy.php on line 1010
Reinstalling wordpress 2.3.1 didn't help.
The problem occurred after I installed the wp-commerce plugin and there is some indication that this was the case with other with this problem. I deleted the plugin but that didn't help, so I went into the database and deleted the tables that wp-commerce created. The problem persisted.
I've tried deactivating all my plugins, but that was no help either.
Any ideas about about where to move next would be greatly appreciated,
