WifiManager Error

[skyark21]

Hi i got this error when I try to compile it.

	"resource": "/home/skyark/Projects/Platformio/Heltec Gateway/lib/WiFiManager-development/WiFiManager.cpp",
	"owner": "cpp",
	"severity": 8,
	"message": "no matching function for call to 'WiFiClass::onEvent(std::_Bind_helper<false, void (WiFiManager::*)(arduino_event_id_t, system_event_info_t), WiFiManager*, const std::_Placeholder<1>&, const std::_Placeholder<2>&>::type)'",
	"startLineNumber": 2901,
	"startColumn": 68,
	"endLineNumber": 2901,
	"endColumn": 68
}]

I'm stuck and dont know what to do.

Maybe u need to check the libraries

[mcenderdragon]

same problem. searching for ESP-WIfiManager like in the read me only made it worse (and there the heagder is called ESP_WifiManager.h and not just WifiManager.h)

[leonardonakagawa]

Hi, Same problem here!

[leonardonakagawa]

Hi just changed for https://github.com/tzapu/WiFiManager Lib, exluding the old WifiManager folder and including the one in the github and worked!!!
