Hi,
Link on title inserted in mailing generate something like : index.php?option=com_content&view=article&id=574:titleslug-name&catid=22
These links generate an error : 1054 - Unknown column '574titleslug' in 'where clause' like if the URL generated is not valid (it collapse the id and the start of the slug escaping the semi column)
Weirdly If I check older newsletter (from january) these kinf of link don't work too. It sounds like a Joomla! issue but these link are generated by acymailing so I can't find where is the issue is coming from...
