Thread:Extension talk:BlockandNuke/Nothing changes after running ban.php

I ran 'php ban.php --hammer' and it went through every user not on the whitelist, "ensuring ban" on each. However, when the process was completed, nothing showed up in the Special:Log/delete or Special:Log/block (but they do show up in the Special:BlockList). I have the UserMerge extension and none of the accounts were merged (I have confirmed that the UserMerge extension is operational). I am running 1.18.2, if that helps.

I tried using the web browser interface at Special:BlockandNuke, but when I click block, it hangs and the window goes white. I have over 27,000 users to get rid of. I would be very grateful for any help. Thank you!
