My HostPapa did it and then sent me this:
Thank you for being so patient while we are working on the issue.
I’ve found that the issue was caused by the dynamic-headers plugin.
I’ve deactivated the plugin as it conflicts with other plugins/themes inside the account.
The issued should be resolved now.
