Hi @executator
I thought you struggle with “Please ensure your entry is valid” error this topic is about setting new redirections, issues with existing redirection is something else and there are no changes to it in above version.
Make sure that “Ignore parameters?” and “Ignore trailing slashes?” option is enabled in advanced options of the redirection.
That should work, there is high chance that something conflicts with our plugin it can be theme or permalink conflict, based on the trace route: https://wheregoes.com/trace/20241067000/
We will check it anyway, would it be possible for you before you apply any changes to export your redirections list and share it with us to:
[ support (at) redirection dot pro ]
Maybe I’ll be able to find something else to make it work with current version, thank you!
