# cd /
# find . -name whmlib.pm
./usr/local/cpanel/whostmgr/docroot/cgi/whmlib.pm
So, this module should be in/usr/local/cpanel/whostmgr/docroot/cgi/ directory.
Try to find it and just copy it in this directory.
Hi akabakov,
no result found same is happened to my second server.
Thanks
To everyone who met this issue!!!
/usr/local/cpanel/whostmgr/docroot/cgi/whmlib.pm is removed in Cpanel 11.62.0.1.
So, please, send me your e-mail in PM and I’ll send this file.
Is this something you can fix before others upgrade to 11.62?
Thank you Akobakov you’re an Angel it works!!!
whmlib is critical software for writing WHM plugins. So I think it was removed in 11.62 (Release Candidate) accidentally and will be added back before release.
Hi Ogeg,
This the response i get from cPanel Development team
The deprecated whmlib.pm module was removed from distribution in cPanel & WHM version 62. Please contact the addon vendor/maker for an updated version that does not depend upon the module.
Hmm…
I have checked module whmlib.pm and found it just collector for some whm modules.
So I will change plugin code and remove whmlib.pm out of it.
Thank you for finding this out so we have time for this fix 
With best regards, Oleg
We’ll release new plugin with fix as soon as possible.
This bug has been fixed in the new CWAF version 2.20.
Please see details:

How do we force an update via the cmd line?
Thanks!
P.S. Just re-ran the client install script and got the WHM interface working again
for cPanel
# /var/cpanel/cwaf/scripts/update-client.pl
or for other cms
# /usr/local/cwaf/scripts/update-client.pl
Regards, Oleg
