Couldn't find Alchemy::Page with 'id'=

[hopewise]

Hello,

I have migrate my app (pre existing before adding alchemy to it) to another server, but I am having a problem migrating content of alchemy cms,

All my database was restored, but only alchemy content was not resotred, I don't know why

Is there some setting I have to do before restore my database? 

I also have this error "Couldn't find Alchemy::Page with 'id'=" when I try to add new page, why?
