Question about cache

[admin]

Well, it next to impossible to tell what was wrong by your description "site stopped working" ...
I need more details

[tubeman]

Site Stopped sending outgoing hits when in config.php we switched from Redis to Couchbase. What more details do you need here?

[admin]

What means " Stopped sending outgoing hits" ?
what did happen when you clicked

[tubeman]

When I click its always going to gallery, not going to trade. After I switch back To Redis then on clicking it opens trades.

You need to turn on out.php debug and see header
Post headers here if you don't understand debug info there

[tubeman]

If out.php is renamed to something else it dosen't matter right? Debug will show the info?

[admin]

yes
