CANNOT IMPORT DATA

For some reason, every time I try to import data (either CSV, XLS, or even pasting it into the form), when I hit 'OK' the page just does not post correctly. I tried the same file on multiple PC's and get the exact same result. This problem seems to be new, since I was able to import data 1 day ago. Did something change with the 'import' function? Any help would be greatly appreciated.

The 'page' erros are below:
