Issues with control panel

Issue

Cannot start the control panel. When trying to start the panel from the console, we can see:

#cd /usr/local/mgr5/
#bin/core ispmgr
terminate called after throwing an instance of 'mgr_err::Error'
 what():  Type: 'crypto' Object: 'decode' Value: 'error:0906D066:PEM routines:PEM_read_bio:bad end line'
Abnormal end 

Solution

Possible cause of this error is an invalid SSL certificate. Delete all the certificate files from the directory /var/www/httpd-cert/ and start the panel:

mv /var/www/httpd-cert/* /root/
