Until recently I was running QGIS 2.18.0 with no issues. Upgraded to 2.18.15. Encountered problem with loading/running the Processing Toolbox plugin, which is important to me in keeping track of specialized raster processing tools that I've used. Could not resolve due to incompatibility of the Processing plugin with 2.18.15. Reinstalled 2.18.0 to resolve, which it did. Problem is that QGIS now consistently takes 8 minutes to start up - pauses at "Restoring loaded plugins". I've tried everything including unloading (but not uninstalling) all plugins - essentially starting QGIS with no plugins. Still takes 8 minutes. Does not crash or generate error messages. Before I do more trials and/or research, are there any fixes that would resolve this? I'm trying to get past the problem without losing settings; etc, such as deleting my .qgis2 folder. System: WIN 7x64 16gb ram SSD (normally a fast machine)
Apparently it's a problem with one of the plugins. You can move the .qgis folder to the desktop and install the plugins again one at a time. Until you identify which one is in trouble. After that, just copy the files to the .qgis folder again.
