Enabling JFBCSystem makes site just blank

Catur,
I'll move this thread to the Joomla 2.5 forum after posting. No worries about the location

As for your issue, that's not an issue we've seen before. Did the installation process go smoothly without any warnings or errors? Please try the following things to see if they can help you resolve the issue:
* Disable the JFBCSystem plugin and any profile plugins you enabled. I can see K2 was enabled, but make sure you disable any others as well.
* Re-install the JFBConnect component. You don't need to uninstall first.
* Try re-enabling *just* the JFBCSystem plugin

If you get the same error there, please try to go to the /administrator/components/com_jfbconnect/assets/facebook-api directory. See if there's a "base_facebook.php" file there. If so, open that file and just look at the text to make sure it's normal letters and no 'garbage' characters in there.

If that file looks right, let us know and we'll have to come up with other things to try. Not sure what's wrong, but we'll help you get to the bottom of it.

Thanks,
Alex

Catur,
Not sure what conflicting plugins could have caused the error you were seeing. The problem sounded like one of our files couldn't be found or read for some reason.

Either way, if you run into other issues or have any other questions, definitely let us know!

Thanks,
Alex

Glad to hear that you figured that out. That definitely would have been an issue, and not something I would have guessed!

Should you need anything else, or run into other issues, just let us know!

Finally, if you haven't already, please consider leaving a rating and review for JFBConnect, or our support, on the Joomla Extension Directory. It's certainly not required, but very appreciated!

Best of luck,
