I'm running V8.0.10824.716 If I try to login from one extension to the User Portal I get the following error: "An exception occurred user_login Error: String was not recognized as a valid DateTime." The only thing I know is that a user tried extensively with a wrong password, that's all. Is there a kind of lockout function? This only occurs on one extension, I can't find anything in the logs, or I'm searching in the wrong logfiles ... I've also tried to restart the services, complete server. Can someone direct me to the right path where to search?
