You say the you downloaded the file "JFBConnect 4.2.5 for Joomla J1.5,J2.5.rar".
That's not a file that came from our site. We've never used the .rar extension and we have never had a package that's compatible with both Joomla 1.5 and Joomla 2.5. Can you tell me the exact filename that you are trying to install that is giving issues?
Also, you made
another post
about an issue that would only occur after installation. Is this still a problem, or is that another site? If that's another site, did the installation go smoothly there?
Thanks,
Alex
