Cannot install SSL for domain

Hi, I have cPanell 11 and there is no way of adding a SSL certify to my domain. I have done an autosigned certified in cPanel, but cannot install as it gives an error when I click on install: '' Template::Exception: [TYPE]=[undef] [INFO]=[SSL::installed_hosts() failed: No dispone de la caracter"stica "sslinstall". ] [TEXT]=[] at cpanel.pl line 1078. cpanel::cpanel::cptt_exectag("/usr/local/cpanel/base/frontend/paper_lantern/ssl/install.htm"..., 1) called at cpanel.pl line 4411 cpanel::cpanel::run_standard_mode() called at cpanel.pl line 879 cpanel::cpanel::script("cpanel::cpanel", "./frontend/paper_lantern/ssl/install.html.tt") called at cpanel.pl line 322 '' any idea?
