The error seems to be from the resizing..in(width+'x'+height+'^'). Do you have imagemagick installed on the server?
@baris I Installed but not working.
Seems to be related to this bug: https://community.nodebb.org/topic/9418/windows-server-2012-problem-again/31
I'll test if the other bugs are fixed too with this.
Edit: Verified this.
I do not know what was the problem, but psychobunny brought back the old version templates.js
This site runs master from github with latest versions of the persona theme.
Can you provide nodebb git revision and database type.
Are you following the steps outlined here?
