Just tried installing the latest version but I get an error with the installer;
Fatal error: Call to undefined function _() in /home/mathsac/public_html/gibbon8/installer/install.php on line 77
Richard, this error seems to suggest that you do not have the gettext module installed in PHP (the _() functions shows that a string should be translated). Please can you run the PHP command phpinfo() in your server environment, and check the output in the browser. Do you see that gettext is enabled?
Thanks. gettext was not enabled. I have installed the module and all works properly now.
