Dear Buddypress,

I have followed the instructions given in this link https://codex.buddypress.org/themes/buddypress-cover-images/, in order to allow the members to upload cover image.I can see the change cover image link and the following texts, but does not see the upload button.
“<Change Cover Image
Your Cover Image will be used to customize the header of your profile.”

So far, I have done the followings:
1. registered the cover image in the functions.php file.
2. updated the members/single/home.php and members/single/profile.php files.
3. Made sure “cover image upload” option is enabled in the buddypress settings.

Can you please let me know what else I need to do to show up the cover image upload button?

Thank you.
