Conversion Failure

[Mefis]

Hello,

I am here to report a bug ask for help. Mainly ask for help to be honest.

I usually have no problems converting books, but for this particular one I am getting this error message, can anyone help?

Thanks in advance!

Upgrade calibre. There were some bugs introduced in 2.21 that affected the handling of classes.

The pseudo-class :visted is not supported

[Mefis]

Ah! Thank you, that worked.
