I see that, problem is the mod is not working. I tried it on another user with permission by him to test it out, but he said nothing occured. The pages didn't slow down, no 404 errors, and yes, I did increase the percentages but nothing affected him.

Installed and and left to it's own devices..

Works perfectly with vBulletin 4.2.4, and I just tested it myself. Very frustrating experience indeed =))

How about vb 4.2.5 does it work? running php 7.1

I am very confident it does...I have it installed on my local dev site (vB 4.2.5/PHP 7.0.13) and it runs without issue.

Okay I just added it. This particular forum was carried over from vb3 which had the MU Mod on it too, and I noticed that I still have the category of MU left over from the vb3 forum so it was pretty seamless to install and set up this vb4 Mod.

One thing I noticed is that when I instant ban someone, the forum gives 100 points and makes the user a MU - I looked and at
AdminCP > User Infractions > User Infraction Manager

I had set it when this was a vb3 forum to make 50 points a MU and 100 points instant ban, so I'm not sure why an instant ban is making someone a MU, versus banned?
It seems like when you give someone 100 points via Automatic Ban, that this Mod accounts for the 50 first, makes him MU, and not banned.
