[Plugin: wp-forum] WP-Forum: several problems, please help

[PatriCSC]

Hello, I am using WP-Forum in my website. I need your help in order to have the forum working correctly. I have 3 problems:
1 – When a user publish a post after clicking on the submit button all that the user can see is a white page: there is no confirmation of the publishing or something like that and there is no return to the forum page, just a white page.
2 – When you try to register there is no error message. For example: if an user tries to register with a username that is already in use the sistem shows a red bar but in the red bar there is no warning message, so the user does not know what is the problem.
3 – When a user forgets the password the procedure for the recovery of the password sends an email to the user that says “to reset your password click here” but there is no link and so the user cannot proceed with the reset of the password.
Could you please help me to solve this problems? Any suggestion will be appreciated.
Thank you!
