I'm not sure if this is the right place to post this, but I'm trying to get this code to work, and I don't understand the error output and what's it's trying to tell me. I have project "A" which is "WiFiManager"-based, and project "B" which is not. Both projects compile successfully on their own in both Arduino IDE's 1.8 & 2.x.
But when I try and incorporate "WIFIMANAGER" into project "B" things fall apart. I'm going to paste the code & error messages here and hopefully someone can help....let me know if you need the actual html code, which resides in SPIFFS. Otherwise tell me where I should post this for better assistance. Thanks in advance!!!!
Within this code if "WIFIMANAGER" is NOT defined, project "B" works fine, once it is defined, errors!
