[QGIS-Developer] Course credits
Hi Guys, I'm trying to top-up credits for QGIS training course. It doesn't seem to update the €0 to correspond with the amount of credits you'd like to update with and the pay with stipe seems to be disabled also. Not sure is this happening for others but just flagging it in case it is.

[QGIS-Developer] QGIS disappeared and now wont install
Hi, I am ubuntu 18.04 and everything was working fine but QGIS then just disappeared on me. I tried to reinstall using the following tutorial: https://www.gis-blog.com/how-to-install-qgis-3-on-ubuntu/ and updated the key to 2019. Everything seemed to install correctly but QGIS is still not installed? I'm completely lost as to where to go from here? Any help would be appreciated.

Hi Jeff, It turns out it is a memory issue. I'm running a loop with pyqgis and after doing the union, it doesn't release the shm or wal gpkg files on the original union inputs. Anyway of releasing these after running each union? Thanks Le gach dea ghui, *Shane Carey* *GIS and Data Solutions Consultant* On Tue, Nov 26, 2019 at 2:33 PM Jeff McKenna wrote: > Not sure.
