Re: [Qgis-user] problem when opening projects in open instance

Just ran into same problem. I created 2 separate .qgz projects using QGIS 3.34.7 under Mac OSX 10.13.6 I transferred the qgz files to a Windows installation of QGIS 3.34.7 and only one would open. The other resulted in the "Unable to unzip file..." error message. Today I will go back to the si

Re: [Qgis-user] problem when opening projects in open, instance

To further clarify: I transferred both .qgz files from a USB disk to the user's Documents directory. One opened, the other gav the "Unable to unzip file..." error. So not a network or shared volume issue. I did not know enough about Windows to try unzipping the .qgz file :-( Back on the Mac sy

It would be very helpful if the Mac download file names included the version info. For example:  "qgis-macos_3_34_7-ltr.dmg"   instead of just "qgis-macos-ltr.dmg" As currently named the only way to determine the version is to download the entire .dmg. Not a problem for those with high bandwidt

If you could upgrade to OS X 10.13 (High Sierra) then you could run QGIS 3.30. That is what I have been using extensively under OS X 10.13.6 running on my Mac mini. However, it appears that QGIS 3.32 requires at least OS X 10.14 Lester Anderson via QGIS-User wrote: Quick query. Which version o

The shapefile you created from your .csv contains only Attributes, NO Geometry. I don't know of a way to easily add geometries, e.g., coordinates. You could have as easily used Layer > Data Source Manager > Delimited Text to read in the .csv into an attributes-only layer.  Lets name it "ATTRIB".

Is the layer CRS a projected CRS, e.g., with units of feet? If a geographical CRS, such as WGS84, measured in degrees Lat/Long it won't work. Also, does the layer include at least 1 polygon?  If not then you'll see "NULL". But I've never seen "nan" in that context. I've used the approach you

Ludwig's excellent solution is the first I would use. However, if there are too many labels then you could use QGIS "expressions" in the vector layers to suppress labeling when the raster is enabled. See Mask plugin which installs a "is_layer_visible" function which might then be used in a vect
