I'm pretty sure it's them too. After creating a support ticket, having them close it on me without resolution (multiple times) I whined enough to get the following message from them.

Hello,

We have reviewed the server and unable to determine the issue. This has to be an issue with the script itself. I checked the errors logs and it is not reporting any 404 errors. This could mean that the script is attempting to pull data from a remote site. We recommend contacting the developers so they can explain what is happening with the script.

root@gator26 [~]# tail -n 1000 /usr/local/apache/logs/error_log |grep fresh
root@gator26 [~]#

Please let us know if you have any further questions.

Thanks,
Josh

Department: Level 2 Support
Status: On Hold
Nothing has been installed or modified at all in the past 6+ months. The error appreared out of the blue.

I really am with HG *without* ad-supported hosting. I have one of their more expensive plans with my own SSL Certificate.

I've gotten little to no support from them. It's more than a little frustrating.

{sigh}
