I was lead to Joomla by a beautiful website, whose source indicated that it was created by something called Joomla editor.
Joomla! is way too annoying. Not convenient at all, unless you have money to spend on modules. The set-up itself was somewhat clean once I got everything configured on the server, but it supports a complexity I didn't need for this project. If you need a lot of complexity to the website (e.g. a blog with many users managing content) it's not for you.
htaccess.txt file to .htaccess at a forum's suggestion. Not sure if that helped.It (looks) easy! Add the option to install extensions from the web, and search for it. Unfortunately this doesn't work for me because of some unknown bug.
sudo chmod -R a+w JOOMLA/This all took me forever to figure out, but it works now!
It seems for my website, I would need this plugin to do it without a ton of effort. It costs $40! So I am either done with this, or will continue by buying the damn add-on. The positive of having a Joomla site is that editing is easy.
