Description

I have problem to compile WiFiManager for Wemos D1 mini board, I even try with Example AutoConnect with out any luck (it's the same even if I select some other board for example Generic ESP8266 board).
All of the boards definitions are updated and all of the libraries are updated to the latest stable releases.

Any help please!

Open the library .c and .h file and replace all occurrences of HTTP_HEAD with HTTP_MYHEAD.
HTTP_HEAD has become a reserved word.
