No matter what I do, I always get the following message: "Your Pretty Link Pro installation isn't quite complete yet. Automatically Upgrade to Enable Pretty Link Pro". When I click on the link, I get a message telling me my plugin is up to date. Afterwards, the above message comes back again.
I'm using WordPress in multi-site mode with 6 sites. I have installed the plugin at the network level and activated it for only one of the sites in the set.
