500 Error in Guides when saving taxa you add/remove photos from

Trying to change this guide taxon from the automatic caterpillar image to an adult photo by removing the cat. image and adding an adult photo but getting 500 error page when I hit save. (not sure why it isn’t the default photo of the adult showing first but that’s a different problem I’m sure)

I have successfully changed guide taxon before, and with this particular guide the first one I changed worked but I can’t get it to work again. I know guides aren’t being worked on so no bug fixes for this, but does anyone know what I’m doing wrong/a work around I can do?

Description of problem:

Step 1: “Edit” guide taxon

Step 2: Add/remove photos of your taxa (this works with any combination- add photo but don’t remove the original; remove og and add new; adding multiple photos; using both “upload photo” and/or “import photo” from any source)

Step 3: Click “Save Guide Taxon” and get 500 Internal Error page
