Hello team,

Greetings.

I have faced some issue regarding your plugin. I know this is minor issue and you can easily resolve it.

steps:
1) Appearance -> Widget
2) Add item as per your requirement in widget (Like: images, Text)
3) save it. it’s working fine
4) Delete any one item from widget like: delete image from widget
5) save it and you can see error like this: Notice: Undefined index: media_image-3

Please resolve me asap.
Thank you in advance.
