  • I have no problem with Opera (v 10.10 + 10.50 alpha).

    Users have this problem too.
    (Opera v10.10 Build 1893)

    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:
    (blank)

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

    Caching exception list:
    wp-comments-popup.php
    wp-links-opml.php
    wp-locations.php

    There is “General Settings”

    Page Caching: Enable/Disk (enchanced)
    Minify Caching: Enable/Disk
    Database Caching: Enable/Disk
    CDN/Type: Enable/Origin Pull (Mirror)

    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?

    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).

    Thank you Frederick, i will do it.

    I want to help you but i’m sorry, old company has terminated my account
    (https://88.255.156.120/~egonomik/)

    Old server spesifications:
    Linux Centos / VPS
    PHP 5.2.10
    2 GB Personal Ram
    2.8 CPU
    cPanel

    New server:
    Linux Shared hosting (no detail)
    PHP 5.2.11
    Ultra320 SCSI, 16GB ECC R. Ram
    Plesk panel

    and no more useful information, details:
    https://www.turhost.com/linux-portal100-hosting.htm

    i hope this information is helpful for you.

    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.

    Frederick, thank you for your understanding. Any idea on when the next release will be?
