> but crash with file ESPEasyWiFiEvent.ino

I have tried these two, could not find "ESPEasyWiFiEvent.ino"
https://github.com/letscontrolit/ESPEasy/blob/mega/src/ESPEasyWiFiEvent.h
https://github.com/letscontrolit/ESPEasy/blob/mega/src/ESPEasyWifi.ino

but without crash. Have chose RAW mode on GitHub, copy&paste, save. close, open.

Comment 2 Kåre Särs 2018-12-30 21:09:05 UTC 
I think the issue is with a custom arduino highlighting file that does not work with libKF5SyntaxHighlighting

*** This bug has been marked as a duplicate of bug 401480 ***
Comment 3 Lothar 2018-12-31 08:18:08 UTC 
Yes, and he knew it.

A hint here would have been nice.
