error

I get 2 notices:

First about giving write permissions to uploads folder. I have checked that and thats ok.
But the message stays.

Second is
Failed to render template “settings.html”. Please ensure the template cache folder wp-content/uploads/mailpoet/cache” exists and has write permissions. Terminated with error: “Unable to create the cache directory.

It’s weird cause in this folder is already a mailpoet subfolder and cache and several other subfolders, so it has worked before.
How to solve this problem?
