This will automatically disable the RSFirewall! plugin, thus the firewall restrictions won't be applied.

If it helps anybody, this is what I ended up with...........
Works fine and if there is a custom string fields in the layout positions (amazon, BNlink, iBook or kobo) that string becomes the image/logo link. Underpopulated logos/images do not show.

The base for folder handling is the JFolder class, found in the /libraries/src/Filesystem/Folder.php file.

Here is a step by step solution that I have found: and it's working very well:

1. Open File Manager
2. Open Folder "libraries"
3. Open Folder "src"
4. Open Folder "filesystem"
5. Right Click on "folder.php" and click Edit.
6. Look for the line, (search = obd): $obd = ini_get('open_basedir'); Comment out that line with // at the beginning so it becomes://$obd = ini_get('open_basedir');
7. Save and Close. And you're down.
