Need Support

I have been fighting with iProperty for days now, my client had the 3.0b version and had (obviously) lots of issues. I upgraded to 4.0.1 and its like a BOMB went off in my site.
White screen of death, errors include missing sql call fields like p.apt and p.freq, PHP 7 does not work, missing file paths etc. I would really like some support, but there is no obvious place to ask for support.
WHERE DO I POST SUPPORT QUESTIONS!?!?!

Hi-- as it says above,

Before posting questions in the forums, please be sure to read the FAQs by clicking on the FAQs link in the sidebar product menu. You must be logged in and have a valid subscription to access the SUPPORT FORUMS.

If your user doesn't have a current subscription, you won't see the link to the support forum. We have no record of your user ever having a subscription. If you're working on behalf of a client with an active subscription, you'll need to use their login to receive support.

I have asked my client for her login info so I can login with her subscription so you will talk to me about your software. Just more hoops to jump through...
