Hey guys - I want to sanity check something with you. I am creating a custom provider but when I try and open the page being served from my provider in Edit mode, it's just showing blank. Specifically, I get the global toolbar and the top row of icons, but everything below that is blank. There is nothing in the JS console to show what's happening and no errors in the epi error log (I'm on Warning level)

To make sure I wasn't going mad I even pulled down the sample from epiwiki and tried that, with exactly the same results.

My package versions (the relevant ones anyway) are as follows:

So... the question is... anyone else had issues recently? I'm about to create a fresh site and go back to 1st principles to log a fault, but I wanted a sanity check from you good people first :)
