PHP5.6 mod_php (dso)

Hey there!

How can I enable Apache handler mod_php (dso), my website works if I am using mod_php(dso) or php-fpm, but When I am using fpm I get this error

“No protocol handler was valid for the URL /index.php. If you are using a DSO version of mod_proxy, make sure the proxy submodules are included in the configuration using LoadModule.”

I could not find any tutorial for this

Thank you so much
