Hi! I absolutely love your theme. I believe I have been using your Asteria Lite theme for about 2 weeks now. 3 days ago, my site crashed, right in the middle of me writing a post, and I have been unable to access my website, or even my admin page, ever since. It simply shows up as a 504 Gateway Timeout Error page. I've contacted my host, and they have tested my plug-ins, and said they are not the cause. Is there any way that it could be caused by the theme? I'm really at a loss - I have no idea what I did - I literally was composing my post one minute, and the next minute the 504 page appeared on both my url and my admin page.
Since the Asteria Lite theme was one of the more recent changes that I can think of making on my site, I thought that maybe you had some advice, or that you may want to be aware of this, since there could be a chance that it might be the theme. Any help or advice of any kind would be greatly appreciated!!!
