[Qgis-user] Graphical modeler error

[ROMAN HG]

Hello,

I am getting an error when trying to use any algorithm in the graphical modeler. Either dragging it or double clicking, and no matter which algorithm I choose, I am getting the following error:

'An error has occurred while executing Python code: 

NameError: global name 'QTextBrowser' is not defined 

Traceback (most recent call last):

Seems like an installation or route problem. Is there any way to fix it without reinstalling? Thank you in advance
