As always, it is important to back up your wallet, especially before making changes to wallet software.
Checking your version
You may check your current wallet version with:
If it is not v1.8.11, you should update the Geth wallet to the latest.
In order to update, run this command in your server's terminal:
curl -sS https://raw.githubusercontent.com/naconner/lamascripts/master/updates/nodes/eth.sh | bash
If successful, it will output 'Ethereum is updated' and your server will be running the latest Geth version.
Afterwards, verify that the earlier version command now outputs the latest.
Additionally, check that the Funding panel in your admin displays your current balance.
