This could happen if your hosting company has a small number for the maximum input fields in forms, or you use a very big number of slides. In either case, only your hosting provider can help you. Please ask the hosting company to increase these settings in the PHP.ini file:
- max_input_vars
- suhosin.post.max_vars
- suhosin.request.max_vars
Alternatively, you can remove unused slides from the allslider.
