When accessed from mobile, my Facebook app now shows "Sorry, something went wrong ..." error message:
It worked well about a week ago. When browsing on desktop game still works well.
Facebook responds with HTTP error 500 (which is "Internal server error" HTTP error code) with such HTML:
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<title>Error Facebook</title>
<div class="fb_header">
<div class="fb_logo">
<img src="//static.facebook.com/images/mobile/chrome/ui/page-header/logo/fb_logo_small.gif" width="77" height="15" alt="Facebook" />
</div>
</div>
<div class="area error">
<strong>Sorry, something went wrong.</strong>
<p>We are working on it and we'll get it fixed as soon as we can.</p>

</div>
<div class="area footer">

What could be the reason?
