I had been running pgadmin4 v2.0 with no issues.
This is happen when i upgraded my postgresql to 10.4
I have encountered a problem where pgadmin 4 v3.0 cannot initialize Query tools
I have uninstall and reinstall the postgresql multiple times but it didn't solve this problem yet.
i also have downgraded the pgadmin4 to v2.0, unfortunately that the pgadmin4 v2.0 now cannot initialized anymore.
I don't know what cause this problem.
I have searched the solution through internet but only find the solution for Ubuntu User
Has anyone ever encounter this problem also for windows 10 x64 user? Please help...
I get the same message when clicking "Query Tool" menu.
If you keep trying this action over and over you may eventually get to the query tool. Sometimes (rarely) it works. You will spawn may processes though in trying this approach. Check the dashboard to see/kill the processes spawned on each launch attempt of the query tool. I have found no other way to get to the query tool. I also cannot revert back to pgAdmin4 version 2. There is no info in the browser dev tools console and I see no info in the pgAdmin4 logs when I click the query tool menu. As stated in another forum using the File/Reset Layout menu may work to fix this issue. I have had limited success with this though.
I am using: pgAdmin4 version3. Windows 10 Pro. PostgreSQL 9.3, 9.6, and 10. FireFox 60.0.1, Microsoft Edge 41.16299.402.0, and Google Chrome (latest version).
