Try to add the layer again to the problematic project and see if it works then.

comment How to align QGIS legend items to the right?
The best approach is to contact a developer or some company offering commercial support directly. The disclaimer just means that the project cannot organize these targeted developments.

comment How to generalize a polygon file and maintain topology in QGIS?
Usually this error means that the geoprocessing failed at some stage. You have to examine the log which is generated while the tools run to see where the error happens.

@Kurt: The stand-alone installer? Not sure which GRASS version it includes. In Processing settings you can specify if GRASS 6.x or 7.x and where it is installed. Try to adjust these configurations to your setup.

comment How to create a mosaic in QGIS with cutline and feathering for Landsat-8 imagery
Feathering would imply that you want to use blurring along the borders. Is that the case? Or do you only want to use the polygon cutlines?

comment Where to find the “contours from points” model in QGIS 2.6?
There should be a Contour script in the Processing toolbox if you are using the latest version. Try that. It seems like the model was removed, it's not in the source github.com/qgis/QGIS-Processing/tree/master/models

Could you clarify what's wrong with RT Mapserver Exporter? Based on the description it seems to do exactly what you are looking for.

Please note that it does not improve the quality of this site to have two unanswered questions about the same issue. That's why I'm closing this as duplicate and putting a bounty on the older question to motivate answers.

Does it still fail if you open the data file in an empty project? Can you share the file?

Please clarify what you want to do, it's unclear to me what you want to select and do with the selection afterwards.

comment QGIS Select overlapped feature
If you have calculated the distance, you could use a rule-based renderer based on this distance to display all points with a small distance in the map.
