Changing app key after installation

Self-Hosted | v4/Legacy

Hi all

I’ve been running my InvoiceNinja install for a few months now and have just realised that my APP_KEY in my .env file is still at its default of SomeRandomStringSomeRandomString.

After changing this value, and despite clearing every cache that I can think of, I’m getting this error:
DecryptException in BaseEncrypter.php line 48:
The MAC is invalid.

Any ideas how I can change my APP_KEY to something else without having to wipe everything and start again?

Thanks

Will

I’m not sure…

One less than ideal option would be to export your data to JSON and re-import it into a new install.
