Support » Plugin: WP Super Cache » Wp 503 Service Temporarily Unavailable Very Frequently

  • I’m using Wp Super Cache.
    But when ever i try to visit my site (I’m not logged in)
    I get this message “503 Service Temporarily Unavailable”.

    Shouldn’t I see the cached pages instead of the error message?

    My blog has an average of 500 visitors online.
    Godaddy Linux “Ultimate Grid Hosting” Plan.

    I’m unable to view 2 to 3 pages continuosly.
    I’m Unable to update my blog (Coz of 503 errors).
    I have to wait till early morning when there are only few visitors online ie., 50 to 100 visitors online.
    I’m unable to moderate/approve comments (Coz of 503 errors).

    But, When I view the page source code, it says wp super cache generated.

    Use PHP caching rather than mod_rewrite and disable features in the plugin (like compression and 304 browser caching) until it works again.

    Or use a different host.


    A 503 error usually means that there are too many concurrent connections to the website. However, unless your site is getting an extremely large amount of traffic, I wouldn’t expect you to hit that limit on an Unlimited plan. This plan can handle at least 600 simultaneous users, which is a lot.

    If you think this really is a concurrent connection issue, you may need to consider getting a different type of hosting plan – ie, a dedicated server or an Instant Datacenter plan.

    If you think that’s not the issue, I would recommend enabling error logs so you can research further. How to enable error logs:
    If you’re unable to determine the cause after investigating error logs, submit a trouble ticket to our Support team for review. You can do that from this page:

    I just wanted to let you all know this .. I’m Very HAPPY !

    I was surprised to note that now (this moment) my site has 1074 visitors online, without any 503 errors .. I signed up to Cloudflare ..

    Wooooooooooo …….. It’s fantastic !

    But I don’t know how long this will last 1
