Hi Sylvia,
Sadly, it's not just your browser....
We're having some issues with the search functionality on our website not talking to the database that sits behind it. We raised the issue with the webmaster last week when it appeared only one or two tours weren't being shown but it seems to be getting worse.
Hopefully it will be fixed again soon.
I'll reply to your other post with the link for the tour so that other travellers can find it if they are looking for it too.
Kindest regards,
Julia
