Block baserd widgets question
-
I am a plugin developer and one of my plugins contains 22 widgets.
When the classic widgets plugin is installed they all work fine at the frontend.At the backend:
Without the clasic widgets plugin, some work, some don’t: the produce errors likeThe “…” block was affected by errors and may not function properly. Check the developer tools for more details
The console reports errors like
Object { code: “invalid_json”, message: “The response is not a valid JSON response.” }

In the mean time i found out that the error was a non existing function.
The reason that the function does not exist is the fact that a php file is not loaded, because it will only load at the backend (i.e. is_admin() returns true).I have proven that is_admin() returns false on the widget activation dialog screen
This code:
<span style="color:red"><b>is admin : '.(is_admin()?'Yes':'No').'</b></span>
produces
This is not what one expects.
BTW, how can i change at the preview the almost black background that makes the text unreadable?
