Hmmm… it must just be something on my setup causing this error then. I installed a brand new clean install of 3.0, only plugin installed is mv-id and still nothing. Then when I added the var_dump() I noticed no changes as well.
Image here.
I guess this is another reason why I should migrate to my new vps, lol
Edit:
Just a quick update, I went ahead and installed the plugin on a blog I already have running on the vps, it functioned perfectly. So it’s got to be something that my old hosting was unable to do, perhaps the fact that it was running on php 5.1.6. Works now though, thanks for this great plugin.
