Not sure if this has been addressed or not but it appears there is a conflict with the use of table name SYSTEM "SYSTEM (R); added in 8.0.3 (reserved)". I think this is why I'm getting a "Error creating database schema" during a new install?
DB Schema: NOT OK(Error creating database schema: [1064] You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'system (name, value) VALUES ('roundcube-version', '2016112200')' at line 1 (SQL Query: INSERT INTO system (name, value) VALUES ('roundcube-version', '2016112200')))
Thoughts?
