Please note: As WPPizza v3.0+ is almost a complete re-write of v2.x, most action and filter hooks as well as template structures alongside some css have changed. Therefore, if you have customised your WPPizza version 2.x, please refer to the documentation below as to how to re-apply/migrate your customisations. If you cannot find the relevant details here please let me know using the contact form and – if at all possible – I will add relevant documentation or perhaps be able to at least point you in the right direction.
Depending on how extensively you have customised the plugin, I am aware that this might result in quite a bit of work. However, to aid further development of the plugin and simplify future add-on and gateway development this was simply unavoidable unfortunately.

For documentation regarding the previous version of the plugin (i.e v2.x) please refer to the relevant codesnippets, documentation and support forum.Sections/links here as well as on wp-pizza.com etc will be updated accordingly and as soon as possible once version 3.x is being released via the WP repository.
