Hi Jorge,

Taken from Matt's response to a similar question (post 2496):

Well, looking at the source code for the authoring tool, I can see that error originates from this function.

It seems it is complaining because it thinks you have either installed the authoring tool from a source other than https://github.com/adaptlearning/adapt_authoring.git or installed the framework from a source other than https://github.com/adaptlearning/adapt_framework.git (or possibly both).

I'm guessing that if you did install from a different repository you need to do a manual upgrade instead.
