Hi @rebas_saber
Please look very carefully at your error message. The problem isn’t with the “articles” folder, the problem is with the file here:
/home/wxnsgxmy/public_html/mediterraneanjournalscom/files/journals/1/articles/534/60f60a4411487.pdf
So this is probably something you need to fix recursively in the entire files/ directory. Just correcting the permission on the articles folder is not enough. I’m not how you’d do that in your web interface, but from the command line you’d do something like:
chmod -R 755 files/journals
Where 755 is the mode. 755 may not be the mode you should use here, typically you want to make this as restrictive as possible and so it depends on who owns the files.
Regards,
Jason
