Secure your standalone scripts used in a Joomla site
Joomla has everything you may need. Right? If you take a look to the Joomla Extensions site, you may agree with this. But, as always, there may be cases, when the above statement is wrong. For specific need he simplest approach may be to use for specific purposes a standalone script. You can solve the problem - apparently - by using Joomla's wrapper feature, and use your scripts as they where part of your Joomla site. Almost perfect solution you may think... but your scripts are directly accessible by their physical URL, not only through the Joomla interface. What you can do about?
A lot. And surprisingly easily.

Server Settings
Joomla specifies certain settings that are recommended for proper functioning of the system. A list of the recommended and actual settings is displayed when you install Joomla. One of the recommended settings is to have 'Display Errors' switched on. This is very useful when developing and debugging a site, but there is a security vulnerability in PHP (not Joomla, but the language in which Joomla was written) which may allow cross-site-scripting attacks when the display errors option is enabled, if you have a script which produces an error.

The mail function has been temporarily disabled on this site
After upgrade to Joomla 3.2 from previous Joomla 3.* versions you might see the above error message in the backend, or, worse, you simply don't receive any e-mail notifications you usually do. And the site worked just fine before the upgrade!!
If you have registration enabled, or you use the site to interact with your visitors/customers the side effects can be really damaging - nobody gets any mails - and you evend don't see any notice about, until you began to dig for the causes, and, for example, try to send a message for yourself from backend. This potentially can roun your online business or community. Apparently everything is OK, all settings are correct, but the mails are simply not sent.
What's the cause and, more important, how you can fix it?

Who is the real author?
The Joomla has a nifty, often used feature, along other information can show the content item's/articles author name just below the title. It's useful especially when the site is maintained by a number of editors and/or contributors. But sometimes - especially when the site is just launched - all authors are the same.

Why my Joomla site is this slow?
Joomla generally is running at an acceptable speed - users aren't seeing differences between an average Joomla site and another CMS'es. But what if they do? What can cause the (sometime unbearable) slowness of some Joomla sites?

You are not authorised to view this resource
Sometimes when you publish a new menu item, and everything seems to be OK, when you try to access the new menu item you just created you hit the wall: instead of the intended content you'll see the following error:
Even more confusing can be the situation when a link which used to work behaves this way. The target content item is published, access rights are set to Public, and you still got this message! What can be wrong here?
