I was using Mambo CMS on my site
The version i used was too old, v 4.5 (1.0.1)
I tried few times to get this upgrade, but could not figure out how to do this with out errors.
Today there was a Mambo/Joomla exploit
So i descided to do some thing on my Mambo Installation, after several try, i got my Mambo upgraded to version 4.5.2.
Joomla is a fork of Mambo server, but seems more active than orginal Mambo, so i upgraded by Mambo 4.5.2 to latest version of Joomla CMS 1.0.10
Now i have to do some changes in Joomla template, so my site look better. Also thinking of installing some SEO MOD for Joomla.
