Broken examples/doc

[dmtzs]

Describe the bug
Wrong examples out of date

you need to update the examples, the actual ones are useless

[skaarj1989]

Everything compiles and works as it used to. Could you explain what you mean?

I receive this errors when I copy your client code that is in the README:

Using Arduino uno R4 WIFI @skaarj1989

[skaarj1989]

Now it's pretty obvious. Either you did not install mWebSockets or have more than one library with a header WebSocketClient.h, and Arduino picks the wrong one.

[dmtzs]

Well I installed this library first when I installed the arduino IDE, also is a new PC and of course I installed the mwebsockets library.
About thebother could be so if there is something then I will uninstall one then (if there's any) will come back later to give an update
