About a year ago I completed a few projects using Ken Taylor's wifiManager library. (https://github.com/kentaylor/WiFiManager/) and have based my projects on his ConfigureOnSwitch sketch. (https://github.com/kentaylor/WiFiManage ... igOnSwitch) I've got another use for it so I picked it up again and I'm getting this compiling error. I haven't changed/upgraded the Arduino IDE so not quite sure what's happening. I made sure I was using Taylors wifiManager.h It's complaning about "error: previous declaration of 'HTTPMethod HTTP_HEAD'". But more than that is above my experience. Here is the full error message. (In the back of my head I thought I remembered their was a configuration option in the IDE but this seems to point to something else. It's not just my new project that is moaning but all the stuff I did last year generates the same error when verifying the code. In my latest attempt I just tried compiling Taylor's example and get the same error. Thanks in advance for guidance on this.
