I've got an "Invalid current value: 16777216" in the default course size. I've increased the size of maximum upload to 100 Mb in the php.ini file. I've manually changed the maxbytes in the site database and in each course. I've restarted the server (both the apache program and the actual physical machine). I've turned on debugging, set to developer. However, when I go through the new course set up process, I get to the point where I've uploaded my files and set up my scorm. When I click the button to "Save and return to course" I get directed to the modedit.php page which comes up blank (I don't even get a debugging window). I then have to log back into the frontpage, as if I've been completely logged out. Any help to resolve this issue would be greatly appreciated. OBTW, I'm uploading a 76 Mb file (well within the new maximum upload size) and videos within my course presentation and I'm using moodle 1.9.7. Thanks!
