Being a bit paranoid I setup my own indexed RPC node and SSH tunnel via private keys
@Acedian The risk is, that person who provides JSON-RPC node to the others, could collect information on what RPC commands are sent from what IP and pass that information to some bad guys, who can visit MNo in his/her home (if his IP is static/not behind VPN).
@Winston84 This error should occur only if your 'RPC user', 'RPC password' GUI parameters don't match 'rpcuser', 'rpcpassword' from your dash.conf file.
Did you open the dash.conf file by executing Dash Core menu: Tools->Open Wallet Configuration File? This should guarantee openning the correct dash.conf file.
Without having access to the machine and more important - without knowledge about Manjaro linux at all, I will probably not be able to help you, but you could try to reinstall gtk-pixbuf by issuing command:/usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/2.10.0/loaders.cache: No such file or directory
