OJS 3 issue with moving folder to the root

I have a very strange issue. I have successfully upgraded a copy of OJS 2 journal in a subfolder. In the subfolder the site is running just fine. But, the moment I move the site from the subfolder to the root, problem appear in the admin panel. I no longer get the drop down links from the ‘setting’ or ‘user and role’ etc. But, the links appear on a page rather than drop down. If I click any of the links I get strange error appearing. Fro example, If click the ‘role’ link I get [I get ‘{“status”:true,“content”:"\n\n\t\t\tHelp\n\t</a>\n\n
\n\t\n\t\n’}. The CSS does seem to work. However, the site works perfectly, if I move back to the subfolder.
OJS 3: http://spaceandculture.in/ojs3ug
Current OJS 2: http://spaceandculture.in
Basically, I am stuck at the very last moment of going live with the upgraded site.
Strangely, if I move he ojs3 folder another domain’s root it works just fine. The problem seems to be with http://spaceandculture.in domain only.

Hi @jbsarma,

I suspect your browser is hitting a Javascript error – you should be able to see it in your browser’s console. I also wonder if your browser is caching something important from your OJS 2.x installation; try a hard refresh.
