@nicpitsch thanks for the bug report. Working on a release for QGIS >=3.4 that should have that fixed.

If you want to try it out before it's published here's the current dev version: https://github.com/BergWerkGIS/VoGIS-Profil-Tool/raw/qgis-v3.x/VoGisProfilTool.zip

Thanks, still an error:

I did uninstall and reinstall the Plugin version 3.0.1 again, always the same error. I'm using QGIS 3.4.1.

@nicpitsch

1. did you use this one: https://github.com/BergWerkGIS/VoGIS-Profil-Tool/raw/qgis-v3.x/VoGisProfilTool.zip

2. I updated the zip ~12hrs ago, in case you downloaded before could you try again? Plugins -> Manage and Install Plugins... -> Install from ZIP should be enough. No need to un-install.

I did download it again a now it works!

Vielen Dank!
