[#4942] strange validation on reg form

When completing the reg form I get this and all fields are erased:

Error
Please enter your name.

You can try it yourself at www.devj3.kiteboarding-windsurfing-spotguide.com/register/registers.html

When you choose "Surfer" there is not even a name field on the form.

Review your conditionals. Looks like PHP side validation is looking for a name field. I've no idea what your validation is set to for your fields, but it could be the your Business Name, First/Last Name, or Name field validation. If issue persists even with CB Conditional disabled then review your Joomla system and user plugins as it could be a 3rd party registration process that acts on Joomla store throwing a validation error.

"it could be the your Business Name"
==> I dont think so because that is no even on the form (for surfer)

"First/Last Name"
==> also not on the form (for surfer)

"Name field validation"
==> is all CB default

"with CB Conditional disabled"
==> the error is not there but that does not solve the problem because I need that conditional to display different sets of fields - so how do I solve this?

"review your Joomla system and user plugins "
==> do I have to disable the Joomla user plugin?

If disabling CB Conditional solves it then you may have a condition not working properly PHP side. Try disabling conditionals 1 by 1 to help find the culprit. Specifically suggest reviewing any fields being double conditioned. I also noticed the surfer fields do not include any Name field at all, which should not be the case. I recommend allowing your first and last name fields for Surfer and see if issue persists.

Now I get "Please enter a valid email address." ... WTF???

and this:
1054 - Unknown column 'access' in 'where clause' SQL=SELECT `name` AS text, `folder` AS value FROM `xz685_comprofiler_plugin` WHERE `type` = 'templates' AND `published` = 1 AND `access` <= 8 ORDER BY 'ordering'

Ok, here is the deal: I cant contiunue this way. For weeks I try to get my site back to where it was prior to the update. CB20 is ruining my project. Either you set up my CB20 the way it worked in CB19 or I have to give up on CB. What a nightmare!

Where can I send the credentials?

I think I tried every possible/impossible combination, even with single name field ... as soon as I use any condition this weird serverside validation kicks in.

I dont want to force my users to put in a name. The system needs a username/password and an email to function - thats it. There must be a solution for that.
