This is a video recording of what it shows when going to the website, safe mode does work.

Hey there, I don’t think it’s related to MaxMindDB.

It looks like it could be one of your customizations as the app ‘loaded’ and I can see the navbar. Have you considered turning them off one-by-one first?

3

I think the problem is the header locale selector.

@nat that’s what I meant with JSON.parse suddenly breaking the site.

4

Yep! This was it - I will mention this issue in the plugin thread so they can look into it.

Thank you :slight_smile:

It also seems unmaintained which is never good
