How can i change the max number of uploads to more than 10?
I am not sure if this works or not because i have not tested it, but you can definitely try.
Edit groupmgr.php
Find
// Create permissible number of file upload boxes box.
echo "<td class=\"tableb\" align=\"center\">";
echo "<select name=\"num_file_upload_{$group['group_id']}\" class=\"listbox\">";
for ($i = 1; $i <= 10; $i++) {
echo "<option value=\"$i\"";
......
and replace it with
// Create permissible number of file upload boxes box.
echo "<td class=\"tableb\" align=\"center\">";
echo "<select name=\"num_file_upload_{$group['group_id']}\" class=\"listbox\">";
for ($i = 1; $i <= 20; $i++) {
echo "<option value=\"$i\"";
....
You can replace '20' by the number of boxes you want.
as Abbas Ali pointed out: not recommended, the max of 10 files is there for a good reason. Youl'll probably run into timeouts.
