I searched everywhere and couldn't find any solution. I'm having an error when publish with Facebook publishing service into an Album with already few images.
The error is "The file could not be written".
I searched everywhere the temporary folder where LR is exporting the image before uploading without any success.
Maybe it failed once and the temporary file is stuck in read only... but i can't find where ! I'm not Mac OS Sierra 10.12 and LR CC 2015.7 (the latest).
Any idea ?
You may be getting this error because the folder that you are trying to write the temporary files before uploading does not have write permission. So chceck the permissions on that folder and fix them to WRITE permission.
Yes, it's very probably that, the problem is that i've no idea of which folder the Facebook publish tool is temporary using...
