Comment on How to Update WordPress Themes by SEO Dave.
Had no other reports of this issue, had a look for this issue in Google and not found anything like it.
The site with the issue is working fine now, with fatal errors they usually take a site out completely.
Was this a temporary fatal error you no longer see? If so might have been a temporary server issue, nothing broken just a bad connection or something.
You are currently running Stallion 6.1, there’s an update (6.2) you should see under “Dashboard >> Updates” and “Appearance >> Themes”, are you seeing these update notifications? If so have you tried updating?
If you can’t use the automated theme update you can still download the Stallion 6.2 zip file and install using FTP.
BTW when I checked your site I see you are using the Stallion built in Google analytics and Google Analytics for WordPress by Yoast v4.2. Not tried the Yoast Google Analytics plugin, if it doesn’t add anything extra I’d stick with the Stallion Google Analytics code, if it’s got extra features (Yoast does some interesting plugins: shame about his WordPress SEO plugin using nofollow :-() use the standalone plugin Google Analytics for WordPress by Yoast only (no point loading analytics code twice).
