Hi Carolyn,
You can change the link in your navigation menu by going to the Appearance section in your WordPress dashboard and clicking on Menus. This is where you can make changes to your WordPress navigation menus.
There is a drop down at the top to select a menu to edit. The items in that menu will be on your right. You can click on the down arrow on the right of any item to open up options for that item including a delete link. You can use that to remove the current events link that isn’t the correct one.
On the left hand side of this screen you’ll see page, posts and other content types that can be added to the menu. I’m not a user of the events plugin that the site is running, so I don’t know how they want you to add it to your navigation. You can use the custom link option to make a link to any URL. They may have a page for you to add.
Sorry for the posts closing before you replied back. They were set to time out after 10 days. I just extended that to give more breathing room.
This may be a time when it’s best to ask the plugin author for help. This is not a plugin that I use and because of that, I don’t know where to tell you to go to make changes or what those changes would be. The plugin has its own support forum on WordPress.org that you can use for questions related to it.
Take care,
Bill
