Hello Richard,
Once again, thanks for your reactivity and for your fast reply.
I'll do what you ask and revert back to you. In the meantime, here is another reply that I have just received from WebHostingHub:
Hello Henry,
Thank you for contacting us. I apologize for the inconvenience that this has caused, but unfortunately on a shared server we will be unable to make those adjustments. The server uses suphp and we will not be able to change this due to the amount of accounts that it will affect. I do apologize for the inconvenience and I do understand the importance of JetPack to a WordPress site.
Here is a link that might help with alternatives if the JetPack is vital to your site's functionality:

Please let us know if you have any further questions; we are more than happy to help.
So it would seem this fix can't be done on a shared server. Are they talking BS or is this true?
And, if it's true, how do we get JetPack running again?
Best Regards,
Henry
