• Ajax - preferred by some, hated by others

  Ajax is not a genuine Joomla technology, it is just one of programming techniques to made a web page more attractive.

• Joomla display a blank page containing "Error" string

  ... and does this randomly, both in frontend and backend, sometimes showing the correct pages, and rarely an error message saying, that "table '#__session' is marked as crashed and last (automatic?) repair failed".
