PerForms 2.4.0
An error occurred!
Error #18: Session not persistent.

  • Can be solved by pressing the browser's back button and trying again. The session may need to be restarted.
    • Also occurs when joomla global config setting "Live Site" protocol does not match current protocol (http / https)

    • Also an intermittent fault when a user logs out of a joomla session, and tries to show a printer-friendly form by clicking the link displayed at the head of the form (in "joomla mode") - sometimes sessions are not initialised immediately... the workaround is to close the printer-friendly window, and click the menu item again (to bring up the form), then click its printer-friendly button, and the popup should work.
