WebIO not detected (Julia)

[XxAakashxX]

I was trying to use Plotly package in Julia(Jupyter Notebook). As I tried the following command:
Plotly.plot(stats["PetalWidth"], stats["Class"])
It returns :

WebIO not detected.

Please read the troubleshooting guide for more information on how to resolve this issue.

https://juliagizmos.github.io/WebIO.jl/latest/troubleshooting/not-detected/****

After applying the steps mentioned on the link like running the following commands:

Pkg.add("WebIO")
using WebIO
WebIO.install_jupyter_nbextension()

And then running these in terminal:

jupyter nbextension uninstall --user webio/main
jupyter nbextension uninstall --user webio-jupyter-notebook

But still the problem remains unresolved! It still keeps saying "WebIO not detected"
What should i do?

Even My WebIO is also shown connected when I see the notebook extension dashboard!

Did you restart the notebook server?

Happening to me as well. Exact same. I did also restart the notebook kernel. I'm running Julia 1.5.3 and WebIO v0.8.15, Interact v0.10.3, Conda v1.5.0 and IJulia v1.23.0

Did you restart the notebook server (e.g., the jupyter notebook command or IJulia.notebook()) -- not just the kernel?

Yes, that was the problem.
