Thread:Project:Support desk/ConfirmAccount extension sql error

I installed the ConfirmAccount(v1.2.0) extension with mediawiki 1.2.0, and everything seems fine. However when I try to create an account I get this sql error:

" A database query syntax error has occurred. This may indicate a bug in the software. The last attempted database query was:

(SQL query hidden)

from within function "UserAccountRequest::insertOn". Database returned error "23502: ERROR: null value in column "acr_id" violates not-null constraint ". " Does anyone else get this error ? Is there a solution ? All I found in google so far mentions something about using Concat instead of || in the code, but I tried to look for acr_id and what could be creating this issue, but I wasn't able to resolve the issue. Maybe its something simple in the configuration or else, in any case I'd appreciate any help with this :)
