[dreed47]

can you please provide the version numbers you're using for the following:

• Arduino IDE
• WiFiManager Library (must use development branch)
• Arduino Json Library
• PubSub Client Library

Also, what specific board are you testing with?

[Danielv123]

Ah, I wasn't using the development branch of WiFiManager. That explains this issue.
