Help – Unable to Edit from Listing – Edit this Listing goes to 404

If I go to a listing I “own,” and click the Edit this Listing button, I get a Nothing Found message.

I turned off all plugins to no avail. The link from the button is:

https://domain.com/listing/listingname/&eid=102814

I used to be able to do this with no problem and I’m wondering if it’s an ownership issue? I had used a plugin to allow a change of ownership and since deleted it, but the ability to change ownership remained.
