There seems to be some dependency of sangomartapi in userman module. Suppose sangomartapi is removed and when I tried to edit/update user info for a user in userman, throwing error. This issue exists only in v16.
Getting below when I tried to update email for an user, attached screen-shot for reference.
"An Unknown error occured while trying to update user data"
Getting below error when I tried to change description of a user, attached screen-shot for reference.
"SQLSTATE[42S02]: Base table or view not found: 1146 Table 'asterisk.srtapi_chat_users' doesn't exist"
Userman : v220.127.116.11
