Hi.

I attempted to change the password for the default administrator and I received the following error:

[User Error] Uncaught PasswordEncryptor_NotFoundException: No implementation found for "blowfish"
POST /admin/security/EditForm/field/Members/item/1/DetailForm

Line 55 in /home/richmond/public_html/sapphire/security/PasswordEncryptor.php

Anyone come across this before? Thanks!

Thanks for taking the time to respond!

We've done a bit more digging around, and it turns out that the developer who built the site (no longer working here) originally installed it in Silverstripe 3.0.1, but then changed their mind and used 2.4.7 - this meant the Blowfish encryption was still in the system, but wasn't compatible with Silverstripe 2.4.7

We were able to delete the Blowfish fields from the database, and the issue was fixed.
