Problem interacting with forum on iOS and OS X safari

[morozgrafix]

I noticed that I’m not able to send replies, open new topics and interact with many buttons on https://forum.magicmirror.builders forums when browsing the site in Safari on my iPhone 6S with latest iOS. Decided to troubleshoot the problem and tried to load it in Safari 10.0.2 (11602.3.12.0.1) on El Capitan 10.11.6 just to find same issues.

Noticed that console log shows this error:
[Error] Failed to load resource: cannot parse response (nodebb.min.js, line 0) -> https://forum.magicmirror.builders/nodebb.min.js?c15a9192-ff07-4dae-b48b-e1d0ff96ef00

and also noticed that footer didn’t load due to the following error:
[Error] ReferenceError: Can't find variable: require Global Code (categories:1008)

I’m not familiar with NodeBB at all and thought it was worth reporting.

P.S. It did work once earlier today on the phone, but for the past 5-6 days I wasn’t able to interact with many elements on the forum site from mobile device.

This can now be closed, I believe that improvements by @paviro have resolved this issue.
