SEFA cache changes 404 error into 200 status

I was trying ho have 404 error pages, I thinked that was the cache component so I uninstalled id. It was the same so I tried to disaple the SefAdvance cache and the 404 error was returned, by enabling it again i first get a 404 error, but when the page is cached it becomes 200.

Do you think this can be solved?

Will check soon, patience please.

Ok, I'll wait, no problem for this.

Anyway I think that people who made changes to their urls and pages became 404 errors should turn cache off as Google will see all those inexistent pages with 200 status wich shows the same exactly html code (the 404 page you've choosen) instead of giving a 400 error. This means duplicated content.

Confirmed and fixed in 5.5.6

Yes, updated and everything works perfectly
