FIND SIMILAR BOOKS (in series) >UNHANDLED EXCEPTION, ATTRIBUTE ERROR
When attempting to search for /find similar books in a series I get the following error:
"Attribute error": FormatsList object has no attribute "replace"
Using Windows 10 Pro 64-bit
and Calibre 2.77.0 (64-bit) - also occurs on Calibre 2.55.0, etc.
Would appreciate help! Really frustrating.
