url friend .htaccess error 500

[ladefensadelima23]

I installed the Joomla, and I finished making the pages, I set a friendly url, use apache mod_rewrite, add suffix to urls.
But it shows an error message for each internal page, only seen the homepage ladefensadelima.uni.cc
A friend tells me that the administrator has to approve the mod_rewrite or something like that.

The error:

http://ladefensadelima.uni.cc/contacto.html
Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, no-reply@x10hosting.com and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.
Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.

Check your .htaccess file.

It should have several

RewriteRule

lines. You must have the

RewriteBase /

above the top one.

If your install is in public_html/joomla (for example), instead of public_html, make it

RewriteBase /joomla/

EDIT/ADD: If that does not help, please post the entire contents of .htaccess here.

I am assuming that Joomla worked before you set the SEO friendly url option.

You are very intelligent, thank you very much.
My file .htaccess was:
# RewriteBase /

My file is modified .htaccess
RewriteBase /

And now it's working fine.
Thanks
