HI, I have a image of my production server, (Taken every night) for testing new features etc. and have restored that to the test server. I have just done the upgrade to 3.1 of the ispconfig system on the test server, also the billing module and during the billing module install got this error: ERROR 1062 (23000) at line 164: Duplicate entry '1' for key 'PRIMARY' ISPConfig Billing module has been installed. Looking though the web interface every thing looks to be working.. I then clicked on one of the item templates and got this error: Table 'dbispconfig.invoice_vat_rate' doesn't exist I don't use VAT (GST in Australia), so how do I fix this issue? Stephen
Found the issue. It was a issue between the keyboard and chair!... Pays to re-download the billing module manual and do the update steps.
