Please note: Customers on our Shared Hosting platform or on a VPS with a maintenance plan do not need to take any action. WebClick will apply the patch on your behalf.

Update:
Technicians continue to assist customers with virtual servers to update their software. We are monitoring the shared hosting servers and tweaking mitigation techniques based on the latest information available.
