Nodemcu exception 29

Hello,

I am running a webserver on nodemcu, this is not the first time I am doing this with the code I am using. However, after running for some time, I get an exception 29, the error message changes if I comment out parts of the code. Error 1 Error 2

I am a complete noob so please try to explain things as much as possible, thanks!

I think this question would do better at the forum for the esp8266 arduino core - it's an esp8266-specific issue, and I have not seen any discussion of errors that look anything like that over here.
