I have been a Moodle user for six years now and I'm scratching my head over what appears to be a bug.
This morning I successfully uploaded a class of students to enrol them. No problem, worked perfectly.
When I went to enrol the next class using the exam same procedure I continually get an error stating "Number of preprocessed record: 0 The uploaded file contains no valid data"
The uploaded file in question is a CSV file of the same exact type of data from the first class set, except that is a differnt set of students without any duplicates. Upon opening it in a text editor it appears like a flawless CSV text file in UTF-8 coding.
I've seen this error reported several times without resolution. I'm running Moodle 2.0.2. Please help!
