The error disappeared meanwhile and I have not a single clue why.
It occured btw. as I logged out.

Ok, seems using the gallery.php and turning off ajax-navigation solved the issue. ??
Thank you guys!

The error appears only if i am logged out.
Maybe also caused from the plugin WP-Super Cache?

Where do i change the permalink-structure from the galllery?

I will try the tip of zaggle.

PHP Warning: Missing argument 2 for wpdb::prepare()

But what should i do now?
