After reading as many of the posts as I could find I asked our ISP (who's pretty good) to adjust the php.ini file to 20MgB upload size.
He's done that and now in the admin area/variables I see my drop down box has gone from a max. of 2MgB to 8MgB (why it's not 20 I don't know)
However when I try to add an assignment the "local" drop down box in the assignment creation has remained at a maximum of 2MgB.
Any ideas? As always appreciated.
