I installed roundcube 0.8.6 on my server a couple of months ago, and it worked fine. Then a couple of weeks ago I got a error message* when I tried to open round cube. The problem is seemingly that file_uploads is set to a wrong value. As far as I can see in my phpinfo the value is set to On.
I then tried to remove the roundcube folder and reinstall it on my server. On the installation screen it fails with the message: 'file_uploads: NOT OK(is 'On', should be '1')'.
I basically do not understand the difference between On and 1. What is the reason for the issue, and how can I solve it?
*(ERROR: Wrong 'file_uploads' option value and it wasn't possible to set it to required value (1). Check your PHP configuration (including php_admin_flag).)
