[MASTeR Library]

Hi All

Just upgraded tonight from Koha 212.11.06.000 to 23.05.00
That all went fine.

The About Koha page now says:
"Warning:


   - Upgrade to 22.12.00.041 [09:43:21]: Bug 30649 - Increase the vendor
   EDI account password field to 256 characters
   ERROR: Exception 'Koha::Exceptions::MissingParameter' thrown 'No
   encryption_key in koha-conf.xml'

Please help.

 Thanking you..
