Edit orders (1.5.4) crashes!

The order to edit opens nicely, but after that it's a nightmare! The Back- and Update-buttons are broken, but otherwise it "seems" ok. Trying to go back or even just update without a change ends with a blank page!:(
Using 1.3.9h.

Yes, it seems the changes weren't all correct. You might want to roll back to 1.5.3. I'll shoot an email to the person who made the changes.

Email received and 1.5.5 was already in the pipeline.
The back button behaviour is one of the old corpses coming out now and was a long time there already and not new with the last update but i will fix it anyway as much of the flaws that are present in this mod from the past.

As written in the original thread 154 was just a quick fix to let the mod work with 139h and none of the real underlying problems are fixed.

kalastaja please report the next time in the support thread because i am watching that one.

With 1.5.5 clicking 'edit' brings up the edit orders screen as expected, but after this my whole admin breaks and no matter what I click next in the admin I get a blank screen.

The only way to fix this is to delete all cookies relating to my site, then it works again!

Dont know if thats related to the same error as above?

If anyone can help, it would be appreciated.
