Well are these users living in a different country? Can you think of any differences between them and the others who are able to log in?

alright the doima guy just made his 4th account and it worked o.O He lives outside of the US..Not sure which country. The rest of the members are from US (who also experience the problem too)

He said he used usernames with "Doima" like "doimatest" "notdoima" and they wouldnt work. Then he used a new name "testworm" and it worked. Reminds me that another member before who couldnt login used a different word for hers too then it worked.

I wonder if the database stored any username with "doima" and rejected any new members with those characters? o.o

Well I do not think so, the script does not filter out specific keywords. Strange.

hmm I see. Thanks for the support btw! I'll keep setting everything up and see how everything turns out ^^
