[Qgis-user] Cannot add sqlite/spatialite layers to qgis (they come in as tables)

[Alex Mandel]

The plugin requires pyspatialite but QGIS itself has the provider built in.

"SpatiaLite version ..: 4.0.0"

Grab an older version of the Spatialite GUI (1.4 or 1.5) or figure out
how to convert your db to the 3.x variant (I believe the release notes
mention this is possible). The metadata table changed between 3 and 4
and QGIS does not have the version 4 stuff yet (it only came out a few
weeks ago).

Thanks,
Alex
