"Script warning: {{tl|cite book}}: this reference has errors; messages may be hidden"
Does anyone know how to find what these errors are and which citations they are on ?. There are multiple cite book lines in the article - none have apparent errors. The warnings only appear in 'edit preview' - and you are not allowed to navigate away from the page without losing new edits !

:[[User:Charles.bowyer|Charles.bowyer]], you provide [[ISBN]]s for editions of books that, as you describe them, predate the invention of [[Standard Book Numbering|SBNs]], let alone the wide use of ISBNs. The ISBN, if provided, must match the edition described. (If no ISBN exists for the edition cited, you might instead provide an informative [[OCLC number]] for the edition. You can find this at [[WorldCat]].) -- [[User:Hoary|Hoary]] ([[User talk:Hoary|talk]]) 11:09, 12 March 2026 (UTC)
::Thank you very much indeed - that has dealt with the issue. 
::Has something changed in the checking process - these things didn't used to raise errors ? [[User:Charles.bowyer|Charles.bowyer]] ([[User talk:Charles.bowyer|talk]]) 18:32, 14 March 2026 (UTC)
