Database Check

Hi, I have a new PHP website where members can refer new members under them into a multi-level downline. New pending members are coming under their correct sponsor but when I activate the account to an upgraded account the new member does not remain under that sponsor. Instead that member goes into the next spot in the overall company downline under the next available member. There is a compression element to the overall company matrix which allows me to compress all members to remove any 'holes' left by cancelled accounts, but this is a manual element that I did not have any plans to use. I don't know if maybe that is the problem. Anyway, I assume it should only be a quick job. A very quick turnaround is needed as the website is live. Thomas
