Thank you very much for your answers!!
I think i get it right, when i upload the entire site get a 500 server error, but with clean modx installation don´t get this, finally i see a php problem setting the local time to spanish ( so instead of November, read Noviembre, used in archivist, i made this change locally and works).
After this, erase all, and re publish the entire site from 0 following all steps.
Now works great, all urls work and loads quick.
I will crop the original slideshow images speed things up ( i upload them im big size to test image + cropping and i forget to upload lighter images ), i also duplicate header chunks for not calling scripts ( like gmap3, colorbox, etc ) in pages that don´t use them.
There was another rule i enabled in .htaccess to remove "www" and this slow the entire site too. I "#" them.
Thanks again for your response.
You can view the site now and tell me if it works fine,

I can disabled indexes from main .htaccess file right? (done)
Cheers!!! Sebastián.
