So, i have now a new problem. My custom fields, associated with templates, are not loading anymore. When i try to create a new page i choose template and no ACF fields are loaded. Fields do appear AFTER hitting update page with choosed template.
WP and ACF PRO are latest.
Do you have error reporting and display turned on? I recently ran into a similar problem and I made the developer aware of it. For me the problem goes away if I turn off display of errors
Yes, this solved my problem. But why is it like that?
There is a PHP error causing the AJAX request to fail. Like I said, I have made the developer aware of it and it will probably be corrected in the next version.
