Error on Parity UI start (not showing accounts anymore)

[alterbert]

I'm running:

• Parity client version: 2.3.0-beta
• Parity UI version: 0.2.7
• Operating system: MacOS
• Installed via: installer
• Fully synchronized: yes
• Network: ethereum
• I tried to restart both Parity UI and Parity Ethereum client: yes

_Your issue description goes here below.
I started Parity UI as always in order to do an ETH transaction. The interface does not load and instead shows first that the parity node can not be reached and with a second error message, the following:

Please attach the following debugging info:
OS: darwin
Arch: x64
Channel: beta
Error: Exit code 1, with signal null.
Please also attach the contents of the following file:
/Users/**/Library/Application Support/parity-ui/parity.log

The parity.log file has this in it:
