Joomla Site Hacked?
<p>Our Joomla website has not been touched by us in a while.  When I went to add new content, we have the following problem.  The initial page displays fine, but whenever you click on any menu item or link we get the following russian text displayed:</p>

<p>Файл ключевиков keys/sharperdevelopment.com.txt пуст или не существует. Пропишите туда хотя бы один ключевик.</p>

<p>Which translates to:</p>

<p>File keywords keys / sharperdevelopment.com.txt is empty or does not exist. Prescribe to at least one of keywords.</p>

<p>Does anyone have any clue as to whether this is a hacking problem or a configuration problem?  A view source on the web page shows no other HTML just the text shown above.</p>

<p>Our Joomla version was just upgraded to:    Joomla! 3.4.8 Stable 
The website is SharperDevelopment.com</p>

<p>And of course this is happening just before we are meeting a new potential client.  Any help or suggestions would be appreciated.</p>
