# Hosted site stuck on loading page (colored dots) (01/18/2023 8:05 AM Eastern)

First happened on Chrome on laptop, then same with Microsoft Edge on same laptop. Same with iPhone.

Ping works.

Also checked sever status at https://status.discourse.org/ and saw all was good.

It is not a fire alarm as we are never so dependent on it that we need it immediately.

Thanks.

It works in safe mode, if that’s any comfort. Specifically, it works when I select ‘disable official plugins’ so that’s going to be something we’re going to need to look at.

Let me see what I can find out.

Update: It’s looking like an update to the Maths plugin may be the culprit. Someone is looking at it now and we should have a fix in soon. Thanks for the report.

Hi, sorry for squatting this thread, but we have the exact same issue on our hosted site https://brian.discourse.group/ since an hour or so (worked fine earlier during the day). Using safe-mode with “unoffical plugins” (do we use any?) disabled fixes it as well.

Apologies, didn’t see your update: disabling the math plugin fixes it for us as well

As the OP I don’t see it that way.

If I had this problem and someone else noted the problem before me I would ring in to let others know it is a problem shared by others.

It is nice to know that a company like Discourse is responsive and open to such.

Thanks for ringing in.

I agree. Knowing it’s happening to more than one site can help us narrow down the cause if we’re not able to spot it straight away. It’s genuinely very useful.

Sorry it was my mistake. It should be fixed and deployed. Let me know if you see any other issue with this, it’s an old plugin and I cleaned quite a lot.

Thanks for the report!

No worries here, thanks for the reply.

After the problem I disabled both MathJax and AsciiMath on our site.

After seeing your reply reenabled them and then checked if the site was responding with a page refresh, it was, and if the MathJax plugins were working using our custom test page and they were not.

In checking history of change for MathJax

noticed your changes with the final one being false for off and last change done by me to enable it.

In checking history for AsciiMath only I made changes today

Should they work now?

If not and this takes a day or more to fix I don’t see it being a problem for us, just wondering.

I will investigate but if theres a regression, it shouldnt be hard to fix. Will keep you updated.

@EricGT ok I checked, this is correctly working, you must have updated the topic (great idea btw) when the plugin was disabled, I rebuilt the HTML and it seems all good

Yes I did edit the title today.

Thanks for the feedback, learned something new, that updating a topic with a plugin disabled could cause such a problem. While I am not a Ruby-on-Rails developer I take it that rebuilt the HTML means a rebake, please correct me if I am wrong.

Thanks for taking the time to look at this, being a developer myself I know such things happen from time to time but taking quick ownership is not so often seen, nice job.

Yes it’s a rebake indeed
