Recently, someone else had problems with pgAdmin4 on Windows 10. This person used the Edge browser to connect and that was the problem. If you use Edge as well, try to use Chrome instead.
I just installed PostgreSQL 11.2 with pgAdmin 4 onto my Windows 10 system with the intention of using it with Python. Everything seemed to go smoothly and in accordance with the video lessons that I am following online, but when I went to open pgAdmin 4 it would not load for me. I see the splash screen come up, but nothing ever starts and I can't even see a process appear in the Task Manager. I'm afraid that my usual development environment is Linux, so I'm a bit out of my element and may need a bit of extra guidance to find the normal debugging tools and system logs. Can anyone give advice as to how I might resolve this? Thanks!
