Well unfortunately, those are notices for language files.

As for the upload failing, first where did you set the upload size? (Php.ini?) Second is the mime type enabled for the type of file you are uploading?

The 50M upload is in the php.ini file. The upload filesize in WFSections is set in the General Configuration of WFSection, and here is what i have there:

Mime Type
application/zip (marked with blue)

The filesize is set to: 20971520 bytes = 20M
