I have resolved this error myself! hehehe
I renamed the .htaccess file and renamed the wp-content folder.
after that I was prompted with the notice that the database should be upgraded. somehow on the old server before the transfer someone screwed up an update and left me with the mess.
after the database upgrade which was ready in a jiffy I renamed the file and folder back to the original names and all was working again.
I doubt if it is nescesary to rename the .htaccess file, but since I did I mention it to be complete in my information
