This error usually appears after fresh csf installation. In my sample it’s on a Directadmin Server. Here is the warning message that was on the top of panel:
*WARNING* URLGET set to use LWP but perl module is not installed, reverting to HTTP::Tiny
In order to resolve this issue, you need just a single command:
[root@server ~]# yum install perl-libwww-perl
This will install all the missing libraries. In my sample it was like this:
Installed: perl-libwww-perl.noarch 0:5.833-5.el6 Dependency Installed: mailcap.noarch 0:2.1.31-2.el6 perl-Compress-Raw-Zlib.x86_64 1:2.021-144.el6 perl-Compress-Zlib.x86_64 0:2.021-144.el6 perl-HTML-Parser.x86_64 0:3.64-2.el6 perl-HTML-Tagset.noarch 0:3.20-4.el6 perl-IO-Compress-Base.x86_64 0:2.021-144.el6 perl-IO-Compress-Zlib.x86_64 0:2.021-144.el6 perl-URI.noarch 0:1.40-2.el6 Complete!
