Hi Jeff, how did you solve your taxonomy problem?

I have tried Altaf’s way and still receive the same fatal error problem.

Hello Isaac, I downloaded the updated files and manually updated the server file. Once I did that I was able to get the site back up. Once I did that I ran the update for taxonomy. I am out at the moment, but when I’m back I can provide more details.

Hey Jeff, thanks for your feedback. Looking forward for your details.
