I have been trying to install the ext_joomsef3_uddeim.zip onto my Joomla 1.5 site. The sh404sef that was previously installed has been disabled and when installing the ext_joomsef3_uddeim.zip I receive the following message:

Warning: require_once(/home/xxxxxxxx/public_html/libraries/joomla/installer/adapters/sef_ext.php) [function.require-once]: failed to open stream: No such file or directory in /home/xxxxxxxx/public_html/libraries/joomla/installer/installer.php on line 216

Fatal error: require_once() [function.require]: Failed opening required '/home/xxxxxxx/public_html/libraries/joomla/installer/adapters/sef_ext.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/xxxxxxx/public_html/libraries/joomla/installer/installer.php on line 216

Can anyone assist me?

Hi,
It seems like there was a problem when JoomSEF was installed. You can install the extension through JoomSEF (JoomSEF -> Manage Extensions -> Install), but if you want to be able to install JoomSEF extensions through Joomla's Extension manager, you can access your website through FTP and manually copy the file
/administrator/components/com_sef/adapters/sef_ext.php
to
/libraries/joomla/installer/adapters

Hi dajo,

Thanks, but it is not working I tried uploading from JoomSEF and had no luck.

Hi dajo,

If the installation is succesfull what should I see in the Plugin Manager as I see the following:
sh404sef offline code plugin
sh404sef similar urls plugin
system - sh404sef

The Components only show the sh404Sef is that correct?

Hi,
I'm not sure if I understand it correctly. Do you have ARTIO JoomSEF installed? Our uddeIM extension can only work with our JoomSEF component, it's not compatible with sh404sef.

Hi dajo,
I have sh404sef installed which I have disabled and could not install the Artio JoomSEF, I believe that I may require Joomla 2.5
