I assume the plugin is still new on the servers? This happens usually when it's trying to add the current bans to the server, so doesn't impact the ability to protect your server. 

Does this only happen once? Or did it happen a few times?

I will have a look at what might be causing this, and push a fix. 

Yes, it still shows even after reloading the mod.

Just an update. Somehow, 0.3.3 Shows a longer error message. No worries I'm in no way of rushing for a fix but helping to try the plugin out. Its a great plugin!

Data/ServerArmour​

@rustkoyak could you please try and unload server armour, then delete server armour folder

Data/ServerArmour​

. and reload again?

I believe the link at "UPDATES" to 0.3.4 is not compelete. :)

Although the main DOWNLOAD tab is working.

I'd deleted the Data Folder. Once loaded, this is what it shows. :)

@rustkoyak Sad that it didn't fix it, however now it tells me exactly why it happened. 
It seems you have a ban of a steamid, that is extremely old, or buggy "76561198017561295, also has no reason. This is where it is happening. 

Will fix this in the next update. 

Ah, glad I could help out. :) Haha!
