Been running IP v1.5.9 for some time now on and decided to upgrade to 1.5.11
I overwritten the files as suggested and run the setup to upgrade the DB which seemed to go OK however when trying to access IP I keep getting redirected to the welcome page saying:
Please install Invoiceplane
[ Setup ] [ Get Help ]
I made sure ipconfig.php was writable and re-run the setup but still the same welcome page.
