Sometime last night my sidebar disappeared, I'm unsure why or how? I cleared my Custom CSS but it didn't do anything.

This is what it looks like.

I'm running on Chrome.

Did you try clicking "toggle side bar" by the clock to see if that helped?

If not that any custom CSS causing issue?

Ugh after a million years on this site I realised that was a thing.

Thanks! :D

you can lock this. :)
