Price Rounding not saving, Styling of product admin missing

[Aazzoo]

First: Somehow my price rounding settings are not saving. This means after a pricing update, all prices have unlogical digits.
Second: The styling of the alidropship/product data part of my product admin is missing, see attached screenshot.



The only relevant debug messages I get are the following:

I've tried disabling all other plugins, but can't find a solution. Any ideas on what to do next?

Since there was no reply till now, I was trying to set up a clean test site in a folder on the same domain, but my licence key is not accepted. This really leaves me no options, to find out what went wrong...
