I've create an article in the module Knowledge Base, put some images in the body and attached a document.
Once I've saved the record the module is no more available showing this message
HTTP: 500 Internal Server Error
In the log file I've this:
Query Failed: select team_id from kbcontentsattachments where id = '539e1d06-be9b-7284-f1cb-57872238fc17';: MySQL error 1146: Table 'crmprd.kbcontentsattachments' doesn't exist.
Looking inside the tables, this particular table do not exist !!!!!
