An error occured while upgrading

[Vasyl]

While upgrading from 3.5.2 to 3.6.0 I received this message:
"Error: Permission denied: unable to create a folder on the server - data/cache/application"
And nothing happened (it dodn't update).
Now if I try to update I receive message:
"Error: SQLSTATE[42S21]: Column already exists: 1060 Duplicate column name 'is_super_admin'"
Notice: Before that I successfully updated many times starting from 3.1.0.

I think you can just change the version in data/config. Seems your espocrm is upgraded.

It worked! Thanks, successfully updated up to 3.7.1.
