A number of folks have reported an error that occurs when logging into this discussion site. The site fails to load and gives a "Fatal Error in Gdn_Database.Query();" error message. It turns out that the database field that logs all IP addresses used fills up eventually if you use multiple IP addresses. I have gone into the database to delete the IP addresses accumulated by accounts thus far. This should fix the problem until the field fills up again months or years from now.
Let me know if anything seems amiss or you have difficulty logging in.
