I've been trying to edit some of the SEF generated links via the JoomSEF URL Manager, but upon saving the link I get the follow message Error Saving URL.

I've tried both editing, and creating new links via the manager, but I get the same error every time.

I'm trying to edit some of the generated links that aren't working correctly to use the alias, which works with the built-in Joomla SEO, but cant, not without going into the database and doing so manually.

Does anyone have any insight to this matter?

Hello,

check that there are no SQL errors logged at your site. If you are getting this error message, either the URL already exists in the database or the INSERT query cannot be done - that may be due to incorrect structure of table (e.g. if you had sh404sef installed before) or permissions.
