Hey these issues was generated by my filters on my functions.php file. I have deleted my filters to add more functionality on my search input and I have added the plugin “Search Everything”.
@John Huebner; hey you are right, “I have deleted my filters from functions.php later added the plugin Search Everything”. This helped my a lot, ACF is working as always, thank you very much for all the help.
Hey I had the same error; to fix it I am getting the id and later the url of that id:
$url = wp_get_attachment_image_src( get_field('the_name_of_my_field', 'option') );
echo $url[0];
Maybe this is not the best practice but works for me.
Hello again @hube2 thank you very much for the help, your solution was awesome for me; it was the best option to fix my issues.
I just want to add that we need to be careful using the correct post ID; is different to use the id of your Advanced Custom Field Group and use the id of the web page where you are using the ACFG.
