@julian I get the "Congrats! So far so good -- please see server log for details" message, but when I comment out the two lines (as suggested), I get this error:EXECABORT Transaction discarded because of previous errors.
I have no idea what that means.
After further research, it seems to be an error caused by redis running out of memory.
After increasing the available RAM for my server to 1GB, I'm still getting this error.
After increasing swapfile size to 4GB, I'm still getting this error.
