Hi Alex, I'm looking at your Suggestions and see those listings. That can be frustrating.
One example is:
Source: <span id='S134'>S134</span> Ancestry.com U.S., Find A Grave Index, 1600s-Current Publication: Name: Ancestry.com Operations, Inc.; Location: Provo, UT, USA; Date: 2012; Repository: [[#R4]] NOTE<i>Find A Grave</i>. Find A Grave. http://www.findagrave.com/cgi-bin/fg.cgi.
This uses the generic FindAGrave link, not one to the actual memorial. That is what is causing the error. There are two ways to combat this:
1) Use the FamilySearch citation, and add in the WikiTree template:
"Find A Grave Index," database, FamilySearch(https://familysearch.org/ark:/61903/1:1:Q2SM-BBZH : 11 July 2016), Nicholas Curry Waugh Bruce, 1912; Burial, Odebolt, Sac, Iowa, United States of America, Odebolt Cemetery; citing {{FindAGrave|74297174}}
2) Use the citation from FindAGrave, and add in the WikiTree template:
Find A Grave, database and images (https://www.findagrave.com : accessed 03 February 2018), memorial page for Nichols Curry Bruce (7 Jan 1824–9 Sep 1912), {{FindAGrave|74297174}} citing Odebolt Cemetery, Odebolt, Sac County, Iowa, USA ; Maintained by Kelly Hunsaker (contributor 47968366) .
I prefer the FindAGrave citation (look at the bottom of the memorial, and click 'Source Citation'). This one has a tombstone, so I wouldn't leave it out of the profile sources.
