  • CSRF Attack

    A Cross Site Request Forgery (CSRF) attack relies on the trust a website has for a user to execute unauthorized requests and or transactions. For example, say a user is logged into their Joomla! websites' administrator interface in one tab and is browsing a compromised site in another tab.

  • Debugging a translation

    You just finished a development of a new component/module/plugin, which has multilanguage support, or just finished a translation of such a Joomla addon and want to doublecheck the result, and don't know how to do it?

These are using known entrance points as administrator logins to most used software solutions to try they chances to break in. So it's a wise move to change these well known locations. But wait! The need to upgrade compatibility may made this difficult, so, how we can do this without changing a line in Joomla code?

  • Save Failed with the Following Error: Invalid Parent ID

    When I have seen first time this error on Joomla 1.6 while tried to save a new article in Article Manager I was lost:

  • User groups

    By default, across all Joomla versions from Joomla 1.0, through Joomla 1.5, Joomla 1.6 to the Joomla 1.7 the basic structure of default user groups is unchanged. The users are generally sorted in 3 main categories, the unregistered/not logged in users, the registered users with frontend only access and the backend users. The exact naming of these main groups are varying across the different Joomla versions, but the default end level groups are the same. The groups and their core permissions are as follows:
