JFBConnect v6.2.4 was the release that finally broke the 2MB mark. We've been trying hard to keep it under that level, but it was finally too difficult to do. If you're seeing that error, it means that your PHP upload limit is set to 2MB.
There's a few ways to solve:
* You can configure Joomla to use the FTP uploader. That's done by setting your FTP credentials in the Joomla Global Configuration area. This is the simplest way and Joomla has this ability built-in for just this type of scenario.
* Edit the php.ini file. The settings you should need would be:
upload_max_filesize="3M"
post_max_size="3M"
For more information on those, or any other ini settings, see:
php.net/manual/en/ini.core.php
The implications are that your site will accept uploads of up to 3MB. This shouldn't be a problem, but the larger you set that value, the large files users could upload (like photos) to your site. However, you shouldn't be using PHP restrictions to prevent that and using options in your extensions to prevent too large of uploads as it would be handled much more gracefully there.
I hope that helps,
