My forum just updated and now the header is not sticky on mobile. Very difficult to navigate or use chat now, how can I resolve this?

[image] Shauny: They are being unresponsive at the moment. We apparently misrouted your ticket :sob: Your forum has been updated to the version including the fix now.

Does it also happen in safe mode?

Ah no that fixes it so it must be a plugin or component right?

I think it’s the chat plugin https://github.com/discourse/discourse/pull/36248 https://github.com/discourse/discourse/pull/36253 You might be able to override these css changes in a custom theme component, but I guess there is a reason why they were added

Hmm it happens unless I tick Disable all client-side plugin customizations

That makes sense. #chat is #official

Do you know what CSS I need to add back in to fix this? I don’t have a lot of time now but want to fix this bug now

It’s already fixed, so it’s surprising you are in this situation if you just updated. The fix is in the release: [image] Commits · discourse/discourse A platform for community discussion. Free, open, simple. - Commits · discourse/discourse

Not working even by adding in the code to my theme: html.ios-device body { overflow: auto !important; } html.ios-device.composer-open body, html.ios-device.has-full-page-chat body { overflow: hidden !important; }

Can you be more precise when you say “I just updated”, was it few hours ago, or actually yesterday?

My host updated it, literally about an hour ago, but in the Admin it says updated a day ago. I guess it’s an older version?
