I bought Alpine Theme from Themeforest.

I was customizing it when I tried to change the placeholder for the Contact and that is all I did.

thereafter I got this error, and also the image I changed it to does not want to show in the background then.

Notice: Undefined index: icon in md_alpine_module_block_view() (line 181 of /home/photocorner/public_html/sites/all/modules/custom/md_alpine_module/md_alpine_module.module).

What could be causing this?
