Sounds like a caching issue...make sure you call the snippets using the non-cacheable tags, i.e. [!Snippet!], or have the page set to non-cacheable. If you still have problems with one or the other, please direct your questions to the appropriate support thread for that snippet.
When I type something in the "search" option it returns to the hompege.
Also I have problems with the MaxiGallery snippet. I can see the "manage Pictures" button but when I click on it, only reloads that page.
Any ideas?
Thanks
