Migrating v2.x -> v3.x customisations
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.
If you have customised your WPPizza version 2.x, please refer to the documentation on this site here as to how to re-apply/migrate your customisations. If you cannot find the relevant details 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 this was simply unavoidable unfortunately.
