To configure redirect URLs I'm trying to follow instructions from the "Configuring Redirect URLs to Integrate the Store with Existing Website" guide:
1. Open the store in the browser 2. Select a hosting plan or a plan group 3. Sign in as an existing customer and enter your Provider account login and password...
When I sign up with the provider's account access credentials, it results with "Login incorrect. Please try again." error. Why?
The functionality has been implemented in PBA-S since version 4.3.4. Most likely your PBA-S version is older.
Upgrade PBA-S to version 4.3.4 or above.
