Please provide any additional information below.

Please check your accounts folder (Bankcraft\Accounts) for a file called "50". If there is one delete it. If there is non, recreate the folder and copy every visible file into the new folder. delete the old one and rename the new one to match the name of the old accounts folder (this ensures that there are no hidden files with such a name). Please report back if this helped. If not, I have to investigate further (Any additional information like config or accounts folder items could help).

Yes there was a 50 account. And that seems to have fixed everything. I then decided to wipe all accounts, not a big deal since its a new server anyway. So with a clean start its back to being the reliable plugs its always been thanks.
