When I click on my notifications they regularly refuse to load in the little side bar thingy and the actual notification page (and private view in general) nearly always 501s and has to be reloaded at least twice; pictures and gif attatchments appear to be much more unreliable, and now when I try to post replies I am often met with an error message and have to resubmit. Basically it's like you have to do everything at least twice in order for it to take and its making me grumpy.
