As the title suggests I came across this problem today, whereby a couple of staff members could not upload files to our VLE! an error kept appearing (see attachment) This error does not appear for everybody, admins, managers etc can access it fine, some Teachers can access it fine whereas others cannot! I have searched for this problem and I have made various changes to roles, user permissions, capabilities etc.. and nothing seems to work :/ even going as far as to give authenticated users the ability to access all repositories doesn't do it!!!
What im also stuck on is why are some teacher accounts with completely the same settings can access it whilst others cant! (edit: upon further testing it appears that all teachers are affected)
Any help and advice would be greatly welcomed as this problem needs rectifying ASAP!
