I just want to store the uploaded images in a folder, not in the database as BLOB stype binay data. So in the "qa-config.php" file, I found and removed this line's comment:
Then I created the folder with name "screenshot" in the root path under Q2A's installation folder. Even I have set the folder permission to 777. But this still did not work, when I entered the admin panel it said:
The directory /screenshot defined as QA_BLOBS_DIRECTORY is not writable by the web server.
