AITpro on "[Plugin: BulletProof Security] Client being blocked while on mobile"

Hi,

I've been using BPS for awhile now without issues as far as I know, but a client of mine just informed me that he is unable to see his site at all if he tries to access it from mobile. I tried turning off BPS entirely and revert to an earlier .htaccess file and that seemed to do the trick, but of course I don't want to leave the site unsecure.

Any idea why this is happening? I'm guessing his IP block is flagged for some reason? Any idea how to grant him (and those in his area) access to his website? It's a local business, so important that others can reach it.

Here is the one error from the log file. There are more of the same, but with a dynamically changing IP of course:

[403 GET Request: August 29, 2016 - 1:33 pm]

Thanks for any help you can give!
