Database change/ cubecart and wordpress

I have my blog (pbmansion.com/blog) and my cubecart store (pbmansion.com). When i go to the blog and than to the store i get:
“Security Warning

Parsed array keys can not contain illegal characters! Script execution has been halted.

It may be possible to fix this error by deleting your browsers cookies and refresh this page.”

I have wordpress in one database and cubecart in another. Is there a way i can get rid of this warning. And don’t say go to the cubecart site because nobody there knows the answer. I have searched google and i have searched here.

Would it help if i made wordpress in the same database as cubecart? Do I need a prefix or something? If so explain everything there is to it.

Let me know!!!

Thank you!
