Unexpected error KeyError -'+(!!'

[Metichi]

I am trying to download a manga from kissmanga and I run into this error and get told to report it here.
Im using the gallery-dl standalone executable v1.13.5 on ubuntu 20.04

Here is the output

Thanks for reporting. Should be fixed in the new release (commit 714566b)

I'm having a similar error today, also from kissmanga. Tried updating to the latest dev version and it didn't help. Was working fine on a few days ago.

@ImportTaste Cloudflare changed its "Checking your browser before accessing kissmanga.com" challenge again. Should be fixed with d17e962
