Showing Slim Application Error - during uploading file

Hi @latticescipub,

I suspect the path you’re using is still not writable by PHP. You might also have to consider the permissions in parent directories. The details will depend on your server, so unfortunately it’s hard for us to give specific directions. You might check a few other posts on the forum:

Some of those posts suggest putting a PHP test script to check file permissions on your server, outside of OJS. This is probably the best way to confirm whether or not your file permissions are set to permit PHP to work with the directory you’ve created.

Note that 777 permissions are never safe to use, so be careful not to leave them that way.
