2 Problems: Image uploader and stat press not working

All of a sudden and it’s seems to have happened at the same time, I cannot upload images to my site and statpress has stopped collecting hits.

This is very bizarre as it was all working this morning – I was blogging as usual, now neither work.

With regards to uploading images, I’ve tried doing so seperately via media and also whilst writing posts (both flash and browser uploader) but neither work.

Any help/advice would be greatly appreciated.
