[Plugin: All-in-One Event Calendar] The plugin is installed, but has not been configured.

I installed the plugin and activated it. Everything worked fine until I entered my first event and the calendar disappeared and I can’t get it back. Here is what the script is saying …

“The plugin is installed, but has not been configured.”

“All-in-One Event Calendar Notice: To set up the plugin: Select an option in the Calendar page dropdown list, the click Update Settings.”

There is no selection or option in the Calendar page dropdown list!!!

Also … When I try to update the plugin I get an error that says … “An error occurred while updating All-in-One Event Calendar: The plugin is at the latest version..”

Do I have a conflict with another plugin?

Thanks in Advance
