I found the solution by myself, in fact there is a bug in Kloxo MR, when you update or cleanup Kloxo, all apache conf files are reedited by default so you have to take care of correcting path to ssl certificates :
ex : in file /home/apache/conf/domains/mydomain.com.conf
correct lines below:
<IfModule mod_ssl.c>
SSLEngine On
SSLCertificateFile /home/kloxo/httpd/ssl/venet0_0___localhost.crt
SSLCertificateKeyFile /home/kloxo/httpd/ssl/venet0_0___localhost.key
SSLCACertificatefile /home/kloxo/httpd/ssl/venet0_0___localhost.ca
</IfModule>
Once you correct path to certificates, it works fine.
There is the same bug when updating kloxo, I need to manually update the following files:
- /etc/php.ini
- /etc/httpd/conf.d/~lxcenter.conf
- /home/phpini/tpl/php.ini.tpl
- /etc/httpd/conf/httpd.conf
Well, it's not long to do it but it's really good to know it.
