The error means that your server is not providing your Joomla site with enough memory (RAM) to render the page. The error (in the instance above) is happening when a file from JFBConnect (openGraph.php) is being loaded. However, that doesn't necessarily indicate that JFBConnect is the problem. Since there can be many files/extensions that run before JFBConnect, any of them may be taking up too much ram. Ultimately, JFBConnect, in your case, would be the proverbial "straw that broke the camel's back".
What I'd recommend is:
* Set the "Enable Debug Mode" setting in JFBConnect to 'No'. Then, see if the error occurs ever time. That will remove our caching logic, which does conserve memory, and may make the error more easy to recreate (which can help resolve it).
* Disable any plugins you you don't need on your site, especially ones in the "System" group. Those plugins run on every page load. If they are doing things you don't want or need, they're just wasting memory and slowing down your site loading time.
* Contact your hosting provider to bump up the memory allowed for your site. Right now, it's at 32MB, which is sufficient for smaller sites with not many extensions, content, or users. For larger sites, I'd recommend at least 50MB. JFBConnect can run on (small) sites with as little as 12MB of RAM, so we shouldn't be hogging too much on your site.
I hope that helps get you going, but if you have any questions, please let me know!
