Memberstack signup form: four ways it fails

A signup does two separate things. It writes a member record, and then it starts a login session in the visitor's browser, which every restricted page checks before it shows anything. If the session does not stick, because the browser blocks the cookie, the redirect runs before the session exists, or the page is cached from an earlier visit, the member record exists but the visitor sees the site as a guest. They try the sign up again, get told the email is taken, and decide the account is broken. Your member list looks correct, so the problem seems to be somewhere else.

• Submit the form with a new address. Does the page say the account was made, and where does it send you?
• Search your member list for that address. Is the record there, with the plan you expected?
• In a private window, open the restricted page without signing in. Does it send you to log in?
• Sign in with the new address on the same page. Does the restricted page open, or bounce you back?
• Turn off any ad blocker or privacy setting and sign up again. Does the session now hold?

A visitor submits the form and sees one of four results. The first is an error on the form, which means no member record was made, and the visitor is still on the sign up page. The second is a success message that never moves on, which can mean the record was made but the redirect failed. The third is a redirect to a members page that shows a login prompt, so the record and the session do not match. The fourth is a members page that opens and then blocks the next page the visitor clicks. Each of these looks like a broken form from the visitor's side.

Start with the member list. If the new address is not in it, the form never submitted, so look at the form itself: a field name that changed, a required field that is hidden, or an error the page hides. If the address is in the list and the visitor is logged out on the restricted page, the session is the problem, so check the redirect and the cookie settings. If the address is in the list, the visitor is logged in, and the next page still blocks them, the plan or gate rule is wrong for that member.

Run the sign up with an address that has never been used, then again with the same address. Use a private window for each run, so an old session does not hide a broken one. Then run the sign up from a phone browser, where the redirect and the cookie handling differ. A simulated test can run the same steps in each case and report where each run ended.

The page a new member lands on is the first thing they judge. If it is a blank panel, or a button that sends them back to the sign up form, the member reads it as a failed sign up, even when the record was made. Write down what that first screen says on each run, and whether it names the member.

Testing onboarding after sign up

Each plan, gate or redirect change can send a new member to a page they cannot open. Run a fresh sign up after every change to the form, the plan or the members pages. Keep one test member on each plan you sell, so you can see what each one opens. If the members area sits behind a login, give the visitors a test account for those pages, not real member details.
