For Joomla beginners, ensure you have PHP 5.2x for potentially bad extensions
I have had some what I thought were bad exceptions doing strange things to my Joomla site. One symptom was the site would disappear and everything would go blank. This could be you do not have the latest PHP. Most extensions seem to require PHP 5.2 so ensure you have it. You can get that by checking in Joomla’s admin back end by choosing Help->System Info. I just wish Joomla Extension developers would highlight this requirement better and bolder. Many Joomla beginners would never think of this.NOTE I now post my TRADING ALERTS into my personal FACEBOOK ACCOUNT and TWITTER. Don't worry as I don't post stupid cat videos or what I eat!
