Itamar WPML Supporter since 02/2016 Languages: English (English ) Timezone: Asia/Jerusalem (GMT+03:00)	Hi, Our developer has already developed a fix for this fatal error with ACFML 2.1.4. here is what you need to do. 1. Take a backup of your site in case something goes wrong. 2. Edit this file with a code editor: /wp-content/plugins/acfml/classes/class-wpml-acf-options-page.php 3. On line 280, replace this: private static function isValidOptionPagePostId( $postId ) { return (bool) wpml_collect( acf_get_options_pages() ) ->first( Relation::propEq( 'post_id', $postId ) ); } with this: private static function isValidOptionPagePostId( $postId ) { return function_exists( 'acf_get_options_pages' ) && wpml_collect( acf_get_options_pages() )->first( Relation::propEq( 'post_id', $postId ) ); } 4. Save the file. This should fix the fatal error. ** Important! Please make a full site backup (files and DB) before you proceed with those steps** We've tried implementing this fix on your site, but we are blocked from editing the plugin files. Can you please try this fix and tell us if it is working? Thanks a lot, Itamar.

Giacomo Torricelli	Hi Itamar, Today, I updated to 2.1.4.1, so I've not been able to test your fix manually. However, everything seems to be working correctly. I need to remove the path on the server from my original message because it contains the domain name; can you help me with that?
