After installing TemplaVoia. and i try to add page content element on page. that time i suddenly received is :
“Sorry, you didn’t have proper permissions to perform this change.”
The following SQL should do the trick and also fixed your problem.
ALTER TABLE pages ADD t3ver_swapmode tinyint(4) NOT NULL default '0'
I hope it will work for you 🙂
Because of this issue your template may not render on front end side.
