"Table '***.#__mt_config' doesn't exist SQL=SELECT value FROM #__mt_config WHERE varname ='version' LIMIT 1 " error appears when installing Mosets Tree
Symptom
When attempting to install Mosets Tree, you receive the following error message in Extension Manager:
Table '***.#__mt_config' doesn't exist SQL=SELECT value FROM #__mt_config WHERE varname ='version' LIMIT 1
Resolution
The error appears because Mosets Tree detects that you have prior installation of Mosets Tree that still exists in your server. To resolve this, remove the following directories from your server:
- /components/com_mtree
- /administrator/components/com_mtree
Once you've removed the directories above, attempt to install Mosets Tree again.
