Copied here is Alex's response to your contact us submission:
Most installation problems happen on hosts where the upload limit is restricted to 2MB or less. JFBConnect is larger than 2MB, so it won't be able to upload on those hosts. In that case, you'll need to upload the .zip file using FTP and then use the "Install from Directory" option in the Joomla installer.
Otherwise, you can ask your host to increase the upload limit to allow the file to install normally.
You can find further detail on this at our
Common Support Questions
under the "The Installation package fails to load" question. If this doesn't help solve your problem, please let us know more details.
