"You do not have sufficient permissions to access this page"

The same happens to me, I’m using the plugin version 1.5.3 on wordpress 3.8.5

Step to reproduce:

1 – go to “manage galleries”
2 – select “view” on a gallery with more than 10 slides
the url now is something like “/wp-admin/admin.php?page=slideshow-galleries&method=view&id=14”
3 – try to go to the second page by clicking the “>” button
it tries to open the url “/wp-admin/admin.php?page=&Gallerypage=2&orderby=modified&order=desc” saying that you don’t have sufficient permissions to access this page.

Actually I think it is just a matter of a wrong url, I saw that the page argument “page=” is missing, so I’ve tried to manually change the url and it worked:

this for page 2:
/wp-admin/admin.php?page=slideshow-galleries&method=view&id=14&Gallerypage=2&orderby=modified&order=desc

for page 3:
/wp-admin/admin.php?page=slideshow-galleries&method=view&id=14&Gallerypage=3&orderby=modified&order=desc

and so on…
