Free Checkout Page for non logged user

How are you trying to restrict levels BCD ?
Does each level give them different access and or time??

Can you please explain what you are wanting to strict?

Each level , no matter what you give it in access, is all controlled at the pages.
So if you put a tick on a page ( right sidebar) for level B only, then anyone signing up for A, C and D wont see this.

or give it multiple ticks for A,B and C and then only D wont see that page.

Does this help??

Ok, try to explain with my bad english…. You want to be member and writing us and we are sending invite code (discount code) and you register our site with level A (perfect way to unwanted and spam person, because we are selecting who can be register)…

You click JOIN US button on our homepage , its go to checkout page for Level A (link – https://xyz.com/membership-account/membership-checkout/?level=1) and can be register…

After, you can change your level (musician, stage artist, painter etc 15 different level) without discount code because its free.

But, if anyone write to browser adress bar for “Level B Musician – https://xyz.com/membership-account/membership-checkout/?level=2 oops anyone can be register easy.

Ok, lets try to restrict non-member or not logged user [pmpro-checkout] [pmpro-membershiplevel] pages.. Problem is now nobody can open register page because joinus button going to checkout level=1 …

So,

we must restrict all free membership levels checout page (adress) to not logged or not member A…
i mean, restrict this adress (Level B Musician) – https://xyz.com/membership-account/membership-checkout/?level=2
