Every few hours my live Magento 188.8.131.52 installation is caching the wrong link URLs for the category navigation menu.
Sometimes they use the wrong form of the domain (without the www and adding an SID get var) in which case users get endlessly redirected to the homepage or, worse, they sometimes redirect to
http://localhost! The same problem also occurs when accessing the backend. Clearing the cache resolves the issue temporarily but it normally resurfaces after a 1-2 hours. Disabling the cache is a temporary fix but obviously not ideal for a production environment.
I’ve never seen this before, any suggestions?
Thanks in advance
