Occasionally our auto installer won't be able to find your WordPress blog. In those cases, we recommend doing a Gallery installation.
Go to your WordPress Plugins menu, and click Add New.
Search for "CoSchedule", and once it is found click Install Now.
Once the plugin is installed, click Activate Plugin.
Now Sign in with your current CoSchedule information, or if you don't have an account yet - sign up here by following the prompts.
