Thanks for taking the time to report this error and it is very helpful. That is a strange error for sure. It's clear that No module named 'whitebox_workflows' would indicate that it is unable to find the Whitebox Workflows library installed. When the frontend first loads, it tries to import the Whitebox Workflows library to see if it's installed right here:

whitebox_workflows_for_qgis/whitebox_workflows_for_qgis_provider.py

Line 56 in 4e46326

__import__('whitebox_workflows')

If it is unable to find the library installed, it then tries to install it using pip, here:

whitebox_workflows_for_qgis/whitebox_workflows_for_qgis_provider.py

Line 60 in 4e46326

pip.main(['install', 'whitebox-workflows'])

Given this first test is contained within a 'try' block, I'm admittedly confused as to why this is not working. Can I ask, does the frontend not load at all for you then? Can you see the tools at all? If so, can any of them run for you, or do you not see the frontend at all?

Hallo, thank you for your answer. I don't see the frontend at all. I see the whitebox workflow marked below extensions, get the delivered error message ... thats it. No frontend, nothing.

Okay, I've just released v1.0 of this plugin, which should resolve this issue. I'm closing it now, but please feel free to re-open it if you encounter this issue after updating the plugin. Thank you once again for reporting this.
