I’ve installed a new instance of Shopware6, after setup wizard I get a blank page for the admin login. Could not find any solutions for this, so gave up a fews week ago.
Just installed sync to my phone and opened the admin url to test, and it works. Somehow there is a bug with opening the adminpage on Firefox 100.0.2 64-bit. Works fine with Edge!
Okay, that’s something different. That is a memory/CPU issue. I had a shared hosting, and the memory 1024 MB was not the problem, it was the shared CPU that slowed down everything.
