Hello,
I hope you’re doing well. I’m sorry for the experience you’ve had so far.
I got the first issue, but the second one is looking fine at my end. How did you added URL in your anchor menu? Did you put just the section ID or the full url?
To look into this issue more closely, could you please share temporary Super Admin access (inside the hidden content box)? I’ll check this and update you as soon as possible.
Please make sure to keep a full site backup before sharing the credentials, just to be safe.
Best regards,
