I managed to install the Softaculous in the CWP (CentOS Web Panel), even though that the auto installer was not working for me, so manual installation did the trick (is this a bug?)
But afterwards, in the non root user access, everytime I try to access the Softaculous link (xxx.xxx.xxx.xxx:2030/softaculous/), it always shows a blank page.
I have tried to use different browsers (Chrome and Firefox), and the results were the same.
Anyone care to share any previous experience on this?
