Unable to create forum question!

Hi,
I have registered to the forum with a valid purchase code, to report a bug on the enfold contact form. (using + in local part of email is not accepted)

Now I am logged in at kriesi.at with my mail to the account and there no button to open a new question/thread/whatever to report the bug above!

(using + character in mails is valid! – see https://fvdm.com/code/plus-address-forwarding-in-postfix for explanation)

btw when I tried to use this mail for this form, the E-Mail input got red and this error occured:
Error in inputfields. Please check. Form could not be submitted.

Please check an give me a shout how this bad situation can be fixed!
Thanks & Best regards,
Florian
