Fix for 1.1.0 fatal error undefined function

Based on the error message, it should be in the class-themify-customizer.php file which would be in the customizer folder in the themify folder in the themify-base folder which would be in the themes folder which would be in the wp-content folder, etc.

Follow the entire folder path of the error message to find it.

About 2/3’s of the way in the file on line 677, there is a “Build a CSS rule” to edit.

The typo is here:
function build_css_rule( $selector, $style, $mod_name, $prefix = ”, $suffix = ” ) {
$mod = $this->get_cached_mod( $mod_name );
$out = ”;
if ( ! empty( $mod ) ) {
if ( ‘font’ == $style || ‘logo’ == $style || ‘tagline’ == $style || ‘decoration’ == $style ) {
// Font Rule
$font = json_decode( $mod );
if ( isset( $font->family->name ) && ” != $font->family->name ) {
if ( isset( $font->family->fonttype ) && ‘google’ == $font->family->fonttype ) {
$user_subsets = themify_base_get( ‘setting-webfonts_subsets’, array(‘latin’) );
$font_hash = $font->family->name . $font->family->variant . $user_subsets;
wp_enqueue_style( ‘custom-google-fonts-‘ . md5($font_hash), themify_https_esc( ‘http://fonts.googleapis.com/css’ ) . ‘?family=’ . str_replace( ‘ ‘, ‘+’, $font->family->name ) . ‘:’ . $font->family->variant . ‘&subset=’ . implode(‘,’, $user_subsets) );
}

Change:

themify_https_esc(

to

themify_base_https_esc(

Save the file.

So far, my test site has been fine with this.

Be sure you have a backup of your site just in case. If this doesn’t work, restore the backup & keep using the previous theme version until a permenant fix.
