Yes, the forum I used to test was this one.

Will file issues on GitHub with videos/pictures soon.

Opera Mini: Categories take very long to load, clicking on a post turns the page blank most of the time.
LG webOS and Wii U browsers: Clicking on a category turns the page blank with only the top bar and loading indicator.
Nintendo 3DS/2DS browser: Works, but icons show up as boxes.

MyBB and PhpBB worked perfectly on all of them. It looks like NodeBB is just a little too complex for simpler browsers...

Opera Mini makes me really worried because a lot of people on poor data plans or phones use that.

I updated to v1.3.0 and now I'm getting a different error when trying to visit the forum

Is there any way to convert a MongoDB database to Redis? Maybe that could fix it for @xidui.

That's not normal at all. 🤔 Could you do ./nodebb log after startup and after MongoDB crashes? Should be weird messages in there.

@xidui Yeah that should be more than enough, my server (I have Redis though) has only 1,5 GB. What operating system are you using?

EDIT: Left my host's (weirdly chosen) username in

I looked into NodeBB's log and I saw this (upon trying to visit the forum):

Is it the same as this?

https://github.com/NodeBB/NodeBB/issues/5145

Again, works perfectly without a subfolder.

BenLubar created this issue in NodeBB/NodeBB

@xidui Oh, it sounded to me like you were just setting up your site.

Is this very recent or has it always been like this?

You can't use Redis?
