Hello,
I’m sorry you had a bad experience trying to integrate TranslatePress with your project.
I’m assuming you’re referring to https://www.ads-software.com/support/topic/incompatibility-with-translatepress-italian/ ? That error is not something we’re in control and it’s usually PHP8 error or relates to a gettext and sprintf issue with existing translations in that particular plugin.
It’s not something we control or are responsible for. We’re also not responsible for you launching a new feature in your project without proper testing. The WordPress ecosystem if extremely complex and simply wishing for things to work doesn’t always make it happen.
Usually we can help you with this type of issues and we try to investigate them. If you still need help with it please let us know via our support forums and we’ll try to have a closer look at the issue.
Best Regards!
