In Joomla! it is possible to show an article's title by default - sometimes you would want this, for example, if you want the page title to be something other than the article name, however it can be most annoying at times!  By default, the "home" page in Joomla! has the title of "Welcome to the Frontpage" so this is what most people google search for when trying to remove page titles! There are two places that you need to turn off "show page title", which are described below:

1. Go to Article Manager, then on the right hand side at the top you'll see a button called "Parameters".  Here you set your "Global Parameters" - i.e. the options you want to apply for all articles, by default.  Note this can be over-ridden on a per-article basis by editing the parameters of each article.  Turn off "Show Title".

2. Go to your DEFAULT MENU. On your default menu (usually Main Menu), the "star" appears by default item on your homepage .  If this is an article, you need to click on the article name to edit the properties, then on the parameters on the right hand side, turn off Show Page Title (or select a more appropriate title than "Welcome to the Frontpage"!
