Description of my issue:
Since a while my WAF config is:
- Enable Bad Behaviour filter: Yes
- Strict Mode: No
- White list IPs: 66.211.170.66

Today, 2 Paypal orders has been blocked by WAF with reason xssshield.
I've checked again my WAF config, removed 66.211.170.66 from Auto blocking IP and Security exception log but got same blocking few minutes after.

Attached Security Log Exception showing the problem.

White list avoid blocking due to bad behavior here we have a 'xssshield'.
Last order yesterday was Ok and I checked my website (diff between 2 backup), nothing has been change since several days.

I'll have to stop orders.
Please help!!!

Just disable XSSShield from the WAF Configuration page. AS I've written many times, XSSShield and Bad Behaviour are two humongous overkills of a feature. They try to do too much, they are not really necessary and they do throw a lot of false positives. It's the downside of having to do heuristics. In all fairness, I have them turned off on my own sites and I haven't bumped into a problem. So, there you have it, just disable XSSShield in clear conscience.

Thanks for your prompt response.

In fact, I've removed a second time 66.211.170.66 but first from Security exception log and then from Auto blocking IP.
Few minutes later, the second blocked Paypal payment has been accepted and a few hours later the the first blocked Paypal payment has been accepted as well!!!

I could disable xssshield as you suggested but when I put 66.211.170.66 in the 'White list IPs' why your extension lets 'Bad behavior' pass through and block 'xssshield'???

The IP whitelist applies only to the Bad Behaviour integration, that's why it is inside a panel which has to do with Bad Behaviour. It doesn't apply to any other protection provided by Admin Tools.
