Hello Sakin, I use Catch Base Pro (sorry about the wrong “CatchPro”), ther was absolutely no error message, and it happened again after I rebuilt the menu. There are exactly 91 pages at the moment, I am trying to design a static website for a public school in Germnany. (Works really great with the slider images on the start page, that was the main reason for my decision!) I used the “menu”-section of “Dashboard”, where you add the menu items by checking them in the small box on the upper left side of the window. No idea how to send a screen shot within this blog… the site is not public until now, because of that no URL, sorry… Best regards Andreas
