This problem is with Opera, can you fix this?
Thank you.

That's odd. I haven't had problems with Opera either.

There's not nearly enough information to identify a problem. What compression setting are you using on the page cache settings tab?

Yes fredericktownes you right, there is page cache settings:

Maximum lifetime of cache objects: 1800 secs
Garbage collection interval: 1800 secs
HTTP compression: gzip and deflate (best)

Don't cache pages for logged in users (checked)
Cache the home page (checked)
Cache RSS / Atom feeds (site, post, post comments) (checked)
Cache URIs with query string variables (blank)

Rejected user agents:
bot
ia_archive
slurp
crawl
spider

Rejected Cookies:

Never cache the following pages:
wp-.*\.php
index\.php

Caching exception list:
wp-comments-popup.php

Is this information enough?
Thank you.

Change "HTTP compression" to gzip only and empty cache.

Now i moved my site to another server and problem is solved by itself.
"only gzip" method is still required?
Frederick Townes
Member

Yes, that is recommended. Is it still possible to test the site against the old server? Is it still online? It's important to know if it's a Opera issue or plugin issue or WordPress issue (with deflate handling).

Unfortunately it's not enough information, I'd really have to do some quick tests to see how different flavors of PHP behave. Thanks anyway.

Hi Frederick,

I've recently come across this issue on a 3rd party site as well and was wondering if it may be related to the very mild browser-sniffing you're doing in lib\W3\PgCache.php and lib\Minify\HTTP\Encoder.php where you seem to lump Opera in with the old IEs? Not had time to test this on a site I control directly, but may be worth a look.

(full disclosure: I work for Opera as Web Evangelist)

I, too, have seen this on other sites. All of the affected sites I've seen are running WordPress 2.9.2 with W3 Total Cache/0.8.5.2 on Apache 2.0 or 2.2 (not sure whether it's version-specific). I am using Opera 10.51 on Windows 7. I'd like to know if redux_splintered's idea reveals anything. I don't use WordPress anymore so I don't have the ability to do any testing.

Just switched bikeportland.org over to using the w3 total cache this weekend. Getting some email from users as well with the same problem:

Technical Specs from one user:
Windows XP SP3
Opera 10.51, Build 3315

I fired up my opera on my mac, and everything looked kosher. I then installed the latest opera on my vmware xp, and sure enough, its getting deflated content but not deflating it.

So Im not sure where the issue lies:
A. opera says it can handle both Gzip and deflate content, but its getting deflate.(shouldnt it get gzip?)
B. Opera *should* deflate it, but doesnt. Stranger still is when I use opera's built in dev tool (dragonfly) and load the page in 'debug mode' it does deflate it.

Anyhow, switching to gzip only for http compression fixed this issue for us. Basically anybody on a windows box with the latest version of opera is not going to see your site if you select "gzip and deflate - best". Perhaps it shouldnt say "best" until this is fixed?

Here is the Raw request headers as reported by opera's dragonfly tool.

The default setting for W3TC is actually gzip and because of this opera anomaly I'm removing deflate from the next release entirely to reduce support inquiries.

That isn't helpful. Please submit a bug submission form from the support tab of the plugin.
