[Lizmap] Publish WFS services in QGIS with Lizmap

[G. Wagner, Wagner-IT]

> Did you keep both "Lizmap" and "Lizmap server" plugin on the server ?
> If so, you should keep only the server one.
> In the next version of "Lizmap" plugin, the server side will be removed. 

Thanks for the tip.
Yes, I had both installed. At first I was a bit confused about the space in the name "Lizmap server".

The tool "qgis-pluin-manager" is very helpful. It is still missing an option to delete individual plugins. 
I have now simply deleted the corresponding directory and restarted QGIS server. After that the corresponding error messages are gone
