Incompatibility with Async

[lbussy]

The upstream is not well suited to use in an Async environment. Reportedly, this will allow it.

Hello Dear @lbussy ,
I am using your wifi manager library that you forked but still I'm getting an error when I'm putting it in my project that has the async web server library.

I hope you have any solution for this, I'm so in need for this library to work.
Thank you a lot.

This is the error:

The original WiFiManager is now updated to support Async. To address the error you are seeing however,:

#define WEBSERVER_H // <- Define this before you import ESPAsyncWebServer lib
#include "ESPAsyncWebServer.h"

[firasRihan]

@lbussy well all the above errors disappeared except this one :

I am using the onDemandConfigPortal example with my code.

Thanks for your efforts

I tried to use the original WiFiManager but it had the same error as the first one

Unfortunately, it's still an include ordering issue. I've never found a better way to get past that than to deconstruct the project (comment out includes) and put it back together again slowly. You will find a nested inclusion somewhere that is responsible.
