IP Geo Block

I am using IP Geo Block plugin to try and prevent malicious file uploads. Anything other than allowing all (Disabling the feature) generates a sync error. What are the MIME/file extensions used so that I can Whitelist them? Or how would I debug the issue to find them? Disabling prior to sync is a fine work around for the moment. I just don’t want to forget to turn it back on. It’s a charity site and you’d be surprised (or maybe not) how often some joker is trying to break in. For what I have no idea.

Other than that, everything is working really well.

Thanks!
