@Leonatus. . .I'm still not able to resolve your problem. I've already tested many Epub2 and Epub3 files on this plugin without any problems at all. I also note that, in the past, one person did report exactly the same problem as you and I was unable to resolve or fix that problem because I could not emulate the fault using the that plugin on my computer.

Since you get this failure with all epubs that are run with this plugin and since no one else has so far reported this problem recently, I suspect that your plugin problem has probably been caused by a setup problem or a system problem on your computer. I mention this because you've said that all your epubs fail with the same "Could not load [tidylib] library" using the plugin and yet when I run various epubs using this plugin on my computer they don't fail.

If you like, I could contact you and send you my email link via MR messaging and you could send me one of the epubs that fails and I will run the plugin on that epub on my computer system to see if I can emulate your problem or not. Please let me know.
