I agree it might but I am forbidden from viewing the page you linked, and therefore cannot complete the contact form.
I have been trying to figure out how to for 7 hours now, so have resorted to using this forum.
The error is 403 Forbidden. I completed the process designed to undo the 403 Forbidden error earlier today. I am hoping to renew my subscription ASAP.
As I tried to communicate, I cannot speak to Plesk through their website. Also, I am not aware of a local phone number where I am right now (New Zealand).
I would appreciate it if anyone can share an email address.
