Followed every instruction, but allways when I try to add a link an push the submit button, the following message appears: "Database error encountered" ... My sites are just on a shared server, but it beats all requirements (safe mode off, Curl on, etc.). I tested JV-E. on three different Joomla sites - one of them was a complete fresh installation (V. 1.5.23) ... allways the same result. Took me a lot of time.
It seems to be a great extension ... if it works. Sorry, but therefor just an average review. I really would like to make it run to test it.
