I have been attempting to change my media mex upload limit from 1M to 1000M, even having my host change my php settings. The support tech from my hosting service mentioned that it may have something to do with a multisite setup, and they do not support that.
I have looked on your forums and maybe there's a possibility there is a setting that I'm missing?
I have opened access to my site for support (candcworldwide.com) if is helpful.
Thanks so much!
