I just downloaded the CComment 5.3.5 file package and tried to install it but it is NOT installing on Joomla 2.5.28 !
The error states it is missing the installation file.
Is there another link on your website I can use to download the file or is it just not working on this Joomla version?
FYI There are various pages giving a 404 on your site most important the demo page.
Thanks,
Elisabeth
