We can't upload any files on OJS 3.3.0.5

Hello,
We are using OJS 3.3.0.5. but we are unable to upload a file, especially PDF in the galleys.
The below are the errors:

PHP Fatal error:  Uncaught League\Flysystem\Exception: Impossible to create the root directory "/home/gtaorguk/ojsdata_thss". mkdir(): Permission denied in /home2/gtaorguk/thss.gta.org.uk/lib/pkp/lib/vendor/league/flysystem/src/Adapter/Local.php:112

Can anyone advise please?
Thank you

Hi @rbabaei30

From your error message, it appears that the permissions on /home/gtaorguk/ojsdata_thss are incorrect. The web server will need write access to this directory.
