If updating worked for you, then the likely issue was that the server is configured to show PHP warning notices. The update fixed a couple undefined index notices that PHP would throw if a variable was used before being defined. That is not a critical error, but the ajax response doesn’t know how to handle PHP notices. On production servers, it is best practice to configure PHP to log errors only, never show them. You don’t want these notices presented to end users. I hope that helps!
There is not a method to mass move entries from one category to another. You can only do that by running a SQL query in phpMyAdmin or similar tool.
The query would be something like this:
UPDATE *_connections_term_relationships SET term_taxonomy_id = X WHERE term_taxonomy_id = 1
* would be the table prefix used for your WP install.
X would be the term ID from the *_connections_terms table for Landlords
1 should be the term ID for Uncategorized, also from the *_connections_terms table.
Also, You should manually adjust the count in the *_connections_term_taxonomy table for both Landlords and Uncategorized. I suggest making note of the counts before doing the query so you can easily figure out what the new counts are.
I think that is it … I’ve never done it myself.
Hope that helps.
