In 5.5 PBA-E control panel branding was announced:
What does this change mean? How switch from POA to PBA is performed on the branded panel?
In PA 5.4 on switch from POA to PBA, PBA domain was used (provider's URL). Even when the customer was logged in to the reseller's branded control panel, when switch to PBA panel was performed, it was possible to find the urls containing the provider's domain.
In PA 5.5 when switching, the system uses the domain the branding is setup on. If you were using some aliases or other workarounds to login to the control panel usign the URL different from the domain on which the branding is setup, please note that after upgrade to PA 5.5 on switching to PBA from POA the branded domain will always be used.
