So i tried updating Membership to Membership2. I did this only because it told me that i could keep all subscription information and membership levels. But now everything is gone and nothing is imported.
I updated plugin to 188.8.131.52 through "Plugins" section of my Wordpress installation. Then i upraded to Membership2 through the pop up that appeaered. It tried to import but i think it failed (crashed) and now i cannot do it.
When i go to "Settings -> Import" in membership 2, i cannot select "Import from Membership (WBMU Dev) checkbox. It is grayed out".
