Looks ok now?

@Reedy still abnormally slow, start at https://commons.wikimedia.org/w/index.php?title=File%3AThe_New_Testament_of_Iesvs_Christ_faithfvlly_translated_into_English%2C_ovt_of_the_authentical_Latin%2C_diligently_conferred_with_the_Greek%2C_%26_other_Editions_in_diuers_languages.pdf and from the page dropdown on the right, pick any of the pages later in the work.

I have seen the similar issue generally with other pdf files when prodding around at enWS, to me the thumbnail generation for these pdfs based on scans have been playing up for at least a week. [I could dig for filenames if it helps, but it has been wherever I have been working, rather than a particular file.]

Maybe i found the problem, after trying differents options on the Abby Fine Reader.

Only the when i uncheck the "Create documents PDF/A" everything works fine.

In a PDF/A, only images without OCR works okey. Common PDF both work okey. PDF/A is a ISO compliant version for archives.
