Issue: Recent changes block often doesnt load.

Is there a specific page where you have noticed this consistently? It always has content for me.

Mostly the main wiki index. Please see bug report 323235.
My browser console (FF) has these errors
Warning: unreachable code after return statement
ERROR: No data-step attribute specified for spinbox.

The warning is related to a Push Notification add-on you are using. It has also caused other error messages that I have seen.

I don't know where the spinbox code is coming from, but I'm not sure why there would be a spinbox in the front-end. Maybe it's related to an admin tool you have installed.

Please note that I am still seeing Redis timeout errors in your logs - at least once every few minutes. If you are running in debug mode, then this timeout error could make some things mysteriously not load, like the activity contents or a deferred image. You should try to resolve your timeout issue as it may cause other problems.

However, even using Firefox and with debug mode active on your main wiki index, I was still not able to reproduce this issue as described.
