Also checked sever status at and saw all was good.

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


It works in safe mode, if that’s any comfort. :slight_smile: 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. :+1:

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. :slight_smile:


Hi, sorry for squatting this thread, but we have the exact same issue on our hosted site 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 :+1:


As the OP I don’t see it that way. :grinning:

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. :+1: :slight_smile:


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{"subject"%3A"discourse_math_enabled"%2C"action_name"%3A"change_site_setting"}

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{"subject"%3A"discourse_math_enable_asciimath"%2C"action_name"%3A"change_site_setting"}&force_refresh=true

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 :ok_hand:

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. :grinning:

Yes it’s a rebake indeed :+1:
