Im using v3.0.2.0.
When trying to add image to the category, the image manager is not working well.
Check the image below.
Please help. Thank you.

There is no folder in the manager.
When I try to upload picture, the following error occured
"Warning: Directory doesnt exists!"
I noticed now that even the products image manager has now become inaccessible.
Yesterday I can use product image manager without problem.
But now, after using category image manager, my product image manager malfunctioned.
I have tried to update the filemanager.php and filemanager.twig from github but still not working.
Please help.
Thank you.
