While working one of the clients server
We saw an issue where going from WHM > plugin > Softacalous and opening it resulted in blank page.
The issue is due to corrupt files in softacalous.
To fix this issue softacalous need to be reinstalled
to reinstall to go
cd /usr/local/cpanel/whostmgr/docroot/cgi/
rm -rf softaculous
cd /home
wget -N http://files.softaculous.com/install.sh chmod 755 install.sh ./install.sh Once done softacalous was working fine
