Support » Plugin: WP Super Cache » [Plugin: WP Super Cache] Problems since updating to latest version

  • The plugin has been working wonderfully for a long time but since I updated to the latest version 1.0, I am experiencing a few issues on my site http://www.idownloadblog.com/

    Problems don’t appear to affect the front end of the site, so that’s definitely a plus, but it affects what we do in the admin panel.

    Sometimes, when trying to create/edit/save a new post, it just won’t do anything. It just takes forever to load and don’t go anywhere, sometimes returning an error. This is for example an error it returned today http://cl.ly/2B210w2Q431H471k3L0O

    Looking at the error logs, I see this problem:

    [14-Dec-2011 14:09:55] PHP Fatal error: Call to undefined function wp_suspend_cache_addition() in /xxxxxxxxxx/www.idownloadblog.com/web/content/wp-includes/cache.php on line 288
    [14-Dec-2011 14:09:55] PHP Fatal error: Call to undefined function wp_suspend_cache_addition() in /xxxxxxxxxx/www.idownloadblog.com/web/content/wp-includes/cache.php on line 288
    [14-Dec-2011 14:09:56] PHP Fatal error: Call to undefined function wp_suspend_cache_addition() in /xxxxxxxxxx/www.idownloadblog.com/web/content/wp-includes/cache.php on line 288

    The error timestamp is exactly the time the error happened, so it’s definitely linked together.

    The problem just happens randomly. It will work a minute, and not the next one. Error appeared on Safari, Chrome, and Firefox.

    This is my set up:

    Advanced: http://cl.ly/160F1o2A1i3d0w1B1Q0t
    CDN: http://cl.ly/3I2t2B2M1I0y0W0T0M0a

    Any advice? Thank you in advance 🙂

  • Well that depends entirely on the site, the Theme your using and the structure of the plugin. This a brief explanation on caching and how it can affect your site. This was my site at the time and I don’t like to risk change when I have a cart installed with everything working. http://www.youtube.com/watch?v=J3hDvNzr88s&list=UU-xDtk0N4cc_u3k0nJZrtnw&index=3&feature=plcp

    sebastienpage – do you have an external object cache installed? Is there a file called wp-content/object-cache.php installed on your server?

    I have a motto Donncha….if it ain’t broke don’t try and fix it 😉

    If you’re still seeing this “undefined function” error, try checking the “Late init. Display cached files after WordPress has loaded. Most useful in legacy mode.” box on the Advanced Settings page. That should help.

    If you’re using mod_rewrite mode then cached pages will load just as fast as before.

    I tried the dev. version again, I still get the white screen in the super cache setting screen. Cannot go further with it.

    bradenmikael – that’s some sort of PHP error. Check your PHP error log and uncomment the error_reporting() line in wp-cache-phase1.php please. It will really help if you can do that.

    Is this still an issue? Can I upgrade to wordpress 3.3.1 and just leave wp super cache as 0.9.9.9? Or is the issue with all versions of wp super cache?

    thinkwired – it’s an issue for a tiny minority of users and appears to be a WordPress 3.3.1+WP Super Cache 1.0 problem. I haven’t been able to fix it yet as I can’t replicate it.

    Uploaded the Super Cache plugin, but got this error message.

    Fatal error: Cannot redeclare apache_request_headers() in /chroot/home/andreasb/andreasbeau.com/html/blog/wp-content/plugins/wp-super-cache/wp-cache.php on line 1543

    Any help welcome!

    That’s bizarre docAkare – there’s code around that which checks if the function exists before defining it!

    Domncha,
    I also have some problems since the last update and I’m trying to fix it. However, I must confess that I don’t understand well the meaning of all those options, so I prefer to left the default choices in order to stay in the safe side of the fence.
    What I like to know is whether the drop-in ‘advanced-cache.php’ was installed by WP Super Cache or by another cache plugin I previously installed and deleted.
    Thanks

    stopthepress – yes, that was installed by WP Super Cache! If you have any problems you can’t fix please check the other threads on this forum or start a new thread!

    Sorry, Donncha. I’m not a programmer. So what can I do?

    Thanks,
    docAkare

    docAkare – I don’t know. Uninstall the plugin and install it again perhaps? If you can, search your plugins for the command apache_request_headers to see if it’s defined elsewhere. Are you using APC or some PHP opcode cache? That might have caused this.

    Have actually been having a similar problem as described here. Have had a few issues since upgrading to supercache 1.0 and the latest wordpress. 1 was our feed would never get updated so I had to turn caching off there. Also we are expereincing the same issue with the Add Posts. we are a pretty high traffic site, with a lot of content. I find that if I clear the cache you can get to the Add Posts page fine, however the larger the cache grows the slower the page gets. After doing some debugging I found the function it gets hung up on is: wp_cache_post_edit(). I hope this helps.
