Recently, the Toolbox of QGIS GRASS plugin can't find modules in my GNU/Linux Debian. When I click on any module, the toolbox reports the message: Cannot find module x.xxx and, after, I have the dialog window options totally empty (see image below).
My system worked nicely until yesterday.
To solve this problem (in my system recently actualized; with QGIS v. 2.8), I uninstall and install QGIS-GRASS system, including configuration files, erase my .qgis2 home and .grassrc6 (I modified my .bashrc too for adapting these changes) files. Nothing took effect.
I found out that the GRASS-QGIS modules are in /usr/share/qgis/grass/modules. My question is: How can I get my bindings to this path again?
Note: GRASS Console and GRASS commands of Processing Toolbox work well; apparently. However, I would like using the Toolbox of QGIS GRASS plugin again for saving time and it can use my already created work spaces.
