Login issue

[Desert Orchid]

I'm not sure what I've done for this to happen but every time I revisit the site I have to login whereas I used to only have to do it after clearing my cache.

I've ticked the box asking to keep me logged in but it seems to be ignoring it.

Any solutions?

TIA.

It's actually happening on every site.

It all started when oddschecker told me I'd used up all my daily allowance so I cleared my browsing history, which I've done several times before, but not with this outcome.
