I already saw the other questions concerning the same problem, but after trying everything described in the answers there, I still have the problem that my saved print compositions do not show the maps. Not only do they not show in the print composer but also in the printed PDF version there's only white.
As I work with bigger compositions with many maps in one file, it would be great if there is a way to "repair" these.
It was mentioned in Map does not appear upon opening print composer in QGIS that this could happen, if you delete or modify the map layer - because it didn't work properly I had to remove my basemap content .
Could this be the reason for this problem and if so, is there a way to repair it?
