Hi @user3617 
We’ve double-checked your widget and noticed that you have a lot of old events that don’t seem to be relevant anymore, but they are taking up your limit. We recommend you to delete all the outdated events, making room for new ones.
By the way, we have a feature request to automatically delete events from the editor. If you’re interested, you can vote for it to not miss any important updates - Removing past events altogether from widget
