I get a message indicating "Loading failed" when trying to credit a donation to a specific personal campaign page. I can successfully Soft Credit to the owner of the page and add "personal campaign page" as the type, but this isn't the same as crediting to a specific pcp. I was able to recreate this on the demo site - see attached.
Any ideas why in one pop up edit screen one auto fill box works but not the other? I got as far as Contribute > Form > PCP.js.tpl but was out of my depth trying to figure out what was wrong.
