enfold update

I’m getting the following error:

Fatal error: Call to undefined function kriesi_backlink() in /home/content/60/8960360/html/amity1/wp-content/themes/enfold/footer.php on line 82

If I delete all the theme folder and reupload the unzipped folder, will this solve the problem? also, would my content and media disappear if i take this route? thanks

I’ve updated the theme via ftp as suggested in your website as below:

Upload the Proper Files to WordPress

Within your account download button, you will typically see the option to download All Files & Documentation or just the Installable WordPress file only.

The easiest way to upload a theme is to download just the Installable WordPress file and upload it in the WordPress admin area:

Log in to your WordPress admin area
Browse to Appearance > Themes
Click on Add New
Click Upload and browse for the theme zip
The theme can also be found in the All Files & Documentation file, but you will first need to unzip this to your computer and locate the theme files within this package.

If you prefer to use FTP, the theme files can also be uploaded manually by placing the theme in your /wp-content/themes/ folder on your server directly and then visiting Appearance > Themes within the WordPress admin area.
