Actually, I found that whenever I try to make any edit on the “Images setup” together with “Slider General setup”, nothing get saved (no matter which “Save Settings” buttons is clicked
Whereas, if I just edit “Slider General Setup”, the general setup is saved no better which “Save Settings” button is clicked.
Since the image paths is saved as a blob, it is difficult for me to manually save it to MySQL, or else I would have done it.
