I have a new forum Xenforo. Before I used VBB forum. I imported database from old VBB forum to new Xenforo forum. Everything seem OK, but when I run Tools -> Rebuild Catch I get server error like this image. And my forum get Server error. Server is die. I must reboot and close my forum. When deactive forum Xenforum server runs OK. I don't know why? Can you help me?
