It is the second time in a week that have lost the information in the project file (.qgs). When I load the project the only informationI see is the groups in the layers panel, but no layers.
I have no idea what went wrong, inspecting the .qgs file I see that all my layers, coniguration layers, data sources and a lot more are there (20k lines !!). My guess is that something could have gone wrong with some virtual layers, so I think I could get ride of them, but how?
I wonder if there is a way to retrieve some data and info in order to setup the project again from the .qgs file to build a project brick by brick and not start from zero.
System information: Windows 7 Enterprise, QGIS version 2.18.14
I tried to use the .qgs~, but the problem persisted
