Tried upgrading to 1.4.8 from the previous version. I wanted to do this as any invoices I was creating requested customers to enter a password. Even though I had not sent them with a required password.
My hosting provider won’t let me change to php 5.4 so I can’t upgrade Invoice Plane.
I then tried to roll back to the previous version but when I tried to download the install files they are no longer available.
Please stop using PHP 5.3 immediately. Using this version is a huge security risk for you and others.
InvoicePlane should work with 5.4 but I recommend using either 5.5 or a newer version.
Well as stated in the upgrade guide you should make a backup of your database and files. If you’ve done this you can delete the current folder and put in the backup’ed files and the database.
