Sorry it took me so long to reply, I hadn't opened calibre in a week, and didn't remember to check here earlier.
Code:
{
"librarything_coll": "All collections",
"librarything_id_column": "#librarything_id",
"librarything_key": "not required",
"librarything_rating_column": "#librarything_rating",
"librarything_sort": "author,title",
"librarything_taglist": "",
"librarything_user": "tlwright",
"max_results": "100",
"probable_match_threshold": "90",
"use_calibre_identifier": true
}
is the contents of my file, and I've attached a screenshot of the error message plus what it looks like after I click the LT match icon in my toolbar.
