If you are using Google Webmaster Tools, Google will ask you to verify your site.
Its default method to verify a site is to ask you to put a small file in the home directory of your site. If you do that in Zenario's public_html directory, it won't automatically work because the .htaccess rules will get in the way.
When a browser (or Google) makes the request for the file (let's call it google0111111111111111.html) the .htaccess file rules will direct the request to Zenario, which will look for a page with that alias name.
To get around this, you will need to edit your .htaccess file to make a custom rule that tells Apache to serve the file directly. Here's the line to add to .htaccess:
RewriteRule ^google0111111111111111.html$ google0111111111111111.html [L]
Just save the .htaccess file and try the verification again on Webmaster Tools.
Please note that this should go at the top of the file.
