After I have updated to 1.18, sometimes action=purge had no effect. I noticed this when I had a php syntax error while developing and hitting purge, nothing changed. Only when I went into page editing and preview, I got the php error. Once, purge doesn't work on a page, I can hit purge a hundred times and it won't work. Then I go into preview and after that, purge works again. Looks like some caching issue, I didn't change anything in my settings and just use default caching settings. This only happens occasionally, not very often. But I am almost sure I would have noticed this if it would have been present in my 1.17 installation since I am using purge extensively every day. I am aware that the action=purge is removed from the url, so this is not because of just pressing F5 or anything. Also, I have no idea how to re-create this, just waiting for the next time this is happening and I am going to notice it. The worst thing about this is, when you are testing some stuff and can't be sure whether purge really has some effect, you might even have a flaw in your extension/template without noticing since the rendered site output still is the previous one until you edit your testing site again.
Daniel: Does this still sometimes happen in a recent version?
Back then I did an awful lot of purge. Right now I do almost none, so i wouldn't know :-/
Not much information here to investigate (nowadays at least), no confirmation by others, and refering to the upgrade to 1.18 which is now obsolete. Hence nothing actionable here unfortunately => Closing the ticket. Sorry. :-/ Please reopen / file a new ticket if this happens again in a recent and supported version.
