Warning - You must set a valid post-process folder in "Post Processing" settings

[Rouzax]

Describe the bug
I keep getting You must set a valid post-process folder in "Post Processing" settings warnings that I previously didn't get.

My Post Processor is not enabled as I always trigger the import with an API call.

They only thing I changed is added a Extra Script in the post process as described here: #3325 (comment)

Not sure if that might be related, all other settings have stayed the same.

To test I just entered a directory in there and I don't get the warning anymore during a Post Process that is called through the API.

[medariox]

There reason you are getting this warning should be because you have "Postpone if no subtitle" enabled, which requires the post-processing folder to be set (that's where it checks for the subtitles). We should probably add a note about that or something.

@medariox, Previously I had that setting enabled and did not get that message.
