Answer
When trying to install the JoomSEF extension, do you see:
Warning: require_once(.../libraries/joomla/installer/adapters/sef_ext.php) [function.require-once]: failed to open stream: No such file or directory in /home/***/****/***/libraries/joomla/installer/installer.php on line 216
Fatal error: require_once() [function.require]: Failed opening required '.../joomla/installer/adapters/sef_ext.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in .../libraries/joomla/installer/installer.php on line 216
or similar error?
This error will occur when you are trying to install the ARTIO JoomSEF extension via the Joomla default installator tool. However, to install JoomSEF extension, you need to use the installer built-in JoomSEF. Check the topic "How do I install a SEF extension for JoomSEF?" or documentation for details on this subject.
