GUI does not work properly

I do not know what happened to my distribution freepbx version 11, tells me that the web server is not working but it shows me amportal, the buttons do not work properly, attached image of how it shows me the main page. I appreciate your help

 

From the CLI: amportal a r

Already tried that and it did not work

cd /var/lib/asterisk/bin
./module_admin download framework
./module_admin install framework
./module_admin reload

many many thanks, worked perfectly. you saved my life
