Error showing up, not sure what to do.

Hi,

I just switched to https and php 7 and now I’m getting the following error on my front end above the content on a page where I’m using the shortcode:

Notice: add_shortcode was called incorrectly. Invalid shortcode name: [fu-upload]. Do not use spaces or reserved characters: & / < > [ ] = Please see Debugging in WordPress for more information. (This message was added in version 4.4.0.) in /home/
xxxxx/public_html/wp-includes/functions.php on line 4137

Thanks for any help,
Cathy
