I’m seeing this HTML error a lot on several Japanese lessons I’ve used before. With every one where this applies, the word is unselectable when attempting to highlight with the mouse cursor.
No idea why this happened, but here’s a lesson with several of them: Login - LingQ
Can you give it another try now? Thanks.
They’re all working again. That’s not the only lesson where this is happening, though.
I checked and the same ‘span class’ code shows up for the kanji that can’t be selected. Not sure how many this has affected otherwise.
