Thanks nigel, I try to completely uninstall and reinstall it, to me seems like the only viable solution, thank you very much for the help you gave me

Hi nigel thanks for the suggestion but the problem is that the repository that I found with fetch python plugins there is, the georeferencer plugin I've found in any repository There is not even in "plugins.qgis.org/plugins/plugins.xml" I did not find nowhere the plugin, you know where I can find?

opening tells me though that has problems with ftools because there is an outdated plugin installed with an older version, but I don't think this is the problem ...

with Fetch Python Plugins I don't find it, What is repository? There is a repository for GDAL georeferencer?
