Hello Jorge,
We started this discussion over email so please let me copy the same information I gave you to be able to keep track of what we said so far.

Regarding your issue, try removing the .htaccess file from your site’s root. If that works in displaying the home page (frontend) and the administrator interface your problem is WAMPServer: by default, it does not have mod_rewrite enabled which is required for Joomla’s SEF URLs (URL Rewriting). You need to enable it explicitly. Then you can copy the contents of Joomla’s htaccess.txt to a file named .htaccess and your SEF URLs will work just fine as documented in
https://www.akeeba.com/documentation/akeeba-backup-documentation/restoration-troubleshooting.html#prbasicts under “Enabling Apache's mod_rewrite”. Let me copy & paste from it (added emphasis):
If you are restoring on a local host, you have to make sure that your server is loading the mod_rewrite module, otherwise you will most assuredly get a blank page or a 500 Internal Server Error.
If you are using WAMPserver on Windows you must note that mod_rewrite is not loaded by default. In order to enable it, you have to click on WAMPserver's tray icon, Apache, Modules and make sure that Rewrite is checked. If not, click on it and wait for the server to restart. This is required only the first time you restore to a WAMPserver installation and only if you have SEF URLs turned on and you are using Joomla!'s .htaccess
file.
Other local servers, like XAMPP, also come with the mod_rewrite Apache module disabled. These servers require you to edit the httpd.conf
or run other system commands. Please consult your server package's documentation for more information on enabling mod_rewrite.
Some live hosts also do not have Apache's mod_rewrite enabled. If trying to use Joomla!'s stock htaccess.txt renamed to .htaccess causes an immediate blank page or Internal Server Error 500 page on your site, please consult your host.
