Hi, I have a WordPress Multisite, which was set up originally by an IT guy on my behalf. Initially, he added the site to his own subscription to WPMUDEV, but later I bought my own subscription. Now there seems to be a conflict on the site. When I click on the WPMUDEV dashboard, I can see his name as the subscriber, and I constantly get a 'Membership Renewal' request. I don't know how to get rid of this! On my own subscription, I can't seem to add the site as a new website. Kindly advise how I can unlink his profile from my site?
