I tried it twice, reverting to the previous version which does not display the error before attempting the upgrade a second time with the same results. * Plugin Author [smashballoon](https://wordpress.org/support/users/smashballoon/) * (@smashballoon) * [11 years, 2 months ago](https://wordpress.org/support/topic/undefined-variable-in-v-231/#post-5866703) * Hey Bill, * Thanks for letting me know.

The change will cause a lot of previously unnoticed errors to appear in working code. * In this case, the logic works either way, whether the variable is undefined or not set to a particular value, the result is the same. But undefined variables can cause some rather odd bugs, so in the long run stronger error checking is a good thing. * Plugin Author [smashballoon](https://wordpress.org/support/users/smashballoon/) * (@smashballoon) * [11 years, 2 months ago](https://wordpress.org/support/topic/undefined-variable-in-v-231/#post-5866862) * For sure, I’ll get this taken care of in an update today guys.

Please let me know if that’s not the case or if you notice any other PHP notices that shouldn’t be there. * John * Thread Starter [billsmithem](https://wordpress.org/support/users/billsmithem/) * (@billsmithem) * [11 years, 2 months ago](https://wordpress.org/support/topic/undefined-variable-in-v-231/#post-5866867) * John, * You neglected to initialize Icon Font Source, causing undefined index errors: * Notice: Undefined index: cff_font_source in …/wp-content/plugins/custom-facebook- feed/custom-facebook-feed.php on line 1791 * Notice: Undefined index: cff_font_source in …/wp-content/plugins/custom-facebook- feed/custom-facebook-feed.php on line 1793 * until you go to to the bottom of the page at Customize->Misc, where I changed Icon Font Source from CDN to CDN and hit save. * Thread Starter [billsmithem](https://wordpress.org/support/users/billsmithem/) * (@billsmithem) * [11 years, 2 months ago](https://wordpress.org/support/topic/undefined-variable-in-v-231/#post-5866868) * And thanks for the prompt update… * Plugin Author [smashballoon](https://wordpress.org/support/users/smashballoon/) * (@smashballoon) * [11 years, 2 months ago](https://wordpress.org/support/topic/undefined-variable-in-v-231/#post-5866869) * Strange, I didn’t get that notice when testing earlier.

Sorry about that. I’ve tested this one extensively and it seems good on my end.
