pingram3541 – Yes, BUT you know how plugins can make another plugin stop working? So can themes. The debugging process is simple: If one specific plugin stops working, turn off the others and switch to the default theme. See if that plugin works. If it does, start turning them back on.
medoor – Only command line monitoring really :/
To see every request made to varnish, use this:
varnishncsa -F "%m %U"
If you want to grab the last purge requests, it’s this:
varnishlog -d -c -m RxRequest:PURGE
And this will show you if the WP button was used:
varnishlog -d -c -m RxURL:.*vhp_flush_all.*
So what I would do is that first command and then leave it open while I press the button, see if the cache is flushing.
Also make sure ANY other caching is off, including things like PageSpeed. (If you’re on DreamPress, ask Tech Support to turn it off for you .)
