Hello Community

I really need ur help, a customer uploaded different files for my "self-created" slideshow. Later he said that he always get an error when joining the new page with the slideshow images (the other sites worked perfectly).

So, since i never saw this error i just deleted the page via MySQL (Sitetree / Sitetree_live).

After that, i receive the following error and i still don't know what to do to solve this problem, please help me!

Also the slideshow does not display for now, i added the following code (<% if Slideshow %>....) so i think it's something about there are no pictures in the slideshow, but i never deleted all the pictures or somethin like that, only this little MySQL action.
