Error description: we had having an error in the site, this error takes our customers to the "404 page not found". this error appears randomly.... so is hard to show you... This is an error because the pages where you go really exist and work, but for something, when you click on any link on site , the system takes you to a "404 not found page" so.... when the users reports that, they think the site is down .... and to "solve" that....we install a "404 to 301" plugin .... to redirect to an user to the Home when he reach the "404 not found page" ... the error is the same... but for logistic issues.... we put this redirection for two reasesons: 1. the customers don't see a error page and dont think the site is down 2. to have a report of how many times the issue is happening.... becasue every time we have a redirection....is cause the problem is happening and.... why i tell you is a cache issue?... you say it is beacause we identified..that if we clean the cache the issue gone... but just for a moment... Like 30 minutes after... the issue appears again... so what we have to do?.... go and clean cache again.... and the issue gone.... but for 30 minutes.... it is a loop... we need to solve it from the root
