Hi!
I opendd ticket "JS script Error Google Maps Api makes the browser unresponsive" but I by mistake put it as resolved.
However, here is what I have encountered
The unresponsive browser problem occur when I’m editing a custom post which contains a post filed group with field containing conditions which points to custom field not present within the custom post. Example: I would like to have a field with a condition. But as I have many custom field named the same but with different slug names (I guess this is another issue as I cannot reuse custom field in other posts or within in the same post(If I create a filed and then remove it I cannot reuse it without changing the slug name even though it is not used in any post field group )) I see a list of custom fields named the same. I then select one of them to use within the condition. If I select a custom filed which a believe exist within the post but in reality the selected custom field is just named as the field within the post but with a different slug which is not present within the field group. No I have a condition that looks correct but it is pointing to a custom field which cannot be resolved when loading the post for editing. When removing all conditions the editing works as it should. I hope this mad it more clear. There is a private message within the old ticket for accessing the site. Please tell if you need a new one.
