Cannot make change to configuration [ERROR 1054]

The table that's shown in the error is related to the Joomla Update manager. I believe the only item we try to set in that table is your subscriber ID so that you can do a direct download from the update manager.

Could you try the following steps:
1. Enter your 'SourceCoast Subscription ID ' in the JFBConnect > Configuration > General Tab > Misc section. You can find it on sourcecoast.com > My Account > My Profile page.
2. Log into sourcecoast.com in the same browser but a different tab.
3. Go to Extension Manager > Updates in your backend and Purge/Find updates.
4. Try to re-save the setting change in JFBConnect.

Let me know if this helps.
