I am having a problem with update

The two plugins you're trying to update are the older jfbcprofile plugins. Those were used with JFBConnect v4.x, but have been replaced with the newer 'socialprofile' plugins which have more features and are compatible with JFBConnect v5 and v6.

There are no updates you need to apply. The best thing to do is go to your Installer -> Manage area and uninstall any 'jfbcprofile' plugins you have enabled. They are no longer necessary or used.

I hope that helps explain, but if you have any other questions or issues, just let me know.

Thanks,
Alex

No problem. I'm glad we could help explain. If you need anything else, just let me 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 certainly isn't required, but is very appreciated:

Thanks,
