Seo4SMF and now no more sites

I installed the latest version from seo4smf
my smf version is 1.1.8
when a user go to a thread she sees the first site.
all links to second site or other brings hem back to the first?
the links next not works, the user can only read the postings on the first site.
have a board more sites, itself, only the boards from the first site its seen??

any idea?

horseman

also here is bug.
Testing your site to see if seo4smf is working for you have 10 sites
when i click on next i see the last post and this thread has now 1 site not 10??
