when install a theme in 4.3 with mysql =>
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 'as Value FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME LIKE 'Category'' at line 1
This error is caused by the Ajax Filters plugin, which is the only plugin that still does not support MySQL. Simply don't install the Ajax Filters plugin and everything should work fine with the theme on MySQL.
p.s: We are currently working to add MySQL support to the Ajax Filters so hopefully we will have them ready soon.
