Hopefully someone will be able to help me out here, this is driving me mad and threatening to ruin this project entirely. I'm at my wits end with it now and beginning to wish I hadn't moved from D6 to D7 so quickly.

I have created a few views, I've used them a lot in the past so I know how they work (or should work), but this has me stumped.

I was using views to retrieve data and create a custom menu block for me, I went to continue working on it today and now get the following error message every time I try to update a view, and since update doesn't work, you can't save anything. This is a complete dead-stop for me, I can't do a thing until I get this fixed. Full error is below;

"The page at [domain] says;

An AJAX HTTP request terminated abnormally.

Debugging information follows.

Path: http://www.domain.com/dev/?q=admin/structure/views/ajax/rearrange/portfo...

ResponseText:

ReadyState: 4"

Please, if anyone has a clue what is going on, or any idea how to fix it, I would be eternally greatful.

TIA

PS - Hopefully this is in the right place.

PPS - I have looked on both google and the drupal forums and couldn't find anything definitive to help me.
