Does the default captcha work?? Remove the recaptcha plugin and test the default one.
No. I removed ReCaptcha because it was preventing people from signing in.
Do you have an MSN that way I can discuss this easier? If so, please PM me.
You also seem to be using jquery while mybb uses prototype. To avoid any conflicts between the 2 frameworks put this in your head section:
<script type="text/javascript">
jQuery.noConflict();
</script>
If that still doesn't fix it, I'll need admin account details to login and look at it better. PM me those.
Nothing happened. I'll set up an admin account for you in a moment.
Putting this here for reference sake, the problem was resolved and the problem was found to be that the recaptcha plugin was not properly installed/reinstalled but was deleted which left some orphaned stuff.
