What is this warning?

  • https://www.onesourcebackground.com

    Clients accessing our site are calling in and saying its not rendering right on their browser and some are calling in with this:

    Warning: Class __PHP_Incomplete_Class has no unserializer in /home/content/p3pnexwpnas10_data01/14/2612314/html/wp-content/object-cache.php on line 520

    Firefox, IE (vers 11), Edge and Safari seem to be having this issue. Chrome not so much. And it’s not consistent which would make me think it’s the Cache. Once on our site and going back to it, it’s cached so it renders fine.

    I’m using a Mac and Chrome and only when I use Safari does our site look strange: Our homepage features a hero image and the first time using Safari the image is super zoomed in. But if I exit and go back, it renders fine.

    Thoughts? It doesn’t look good for prospects or clients. Please help!! ASAP!!

    Hello onesourcebackground I am getting the same error, and have no idea why, the error is random at showing up and once i got multiple errors like the folloiwng:

    Warning: Class __PHP_Incomplete_Class has no unserializer in /home/content/p3pnexwpnas10_data01/33/2567433/html/wp-content/object-cache.php on line 520

    No idea why i went to those lines in the php but I dont know enough if it is wrongly written, but im sure it has to do with wordpress new version.

    I had it for my site tbsmo.com

    Same error. Maybe because of some recent updates. 4.5.1. Flushing the cache and refreshing the page works but still can’t get rid of it completely.

    This is because of godaddy caching, not a plugin that you have installed. Contact godaddy support and tell them to clear your cache. Seems to be an issue for many people suddenly who are using godaddy wordpress hosting.

    Ok but some are saying its not getting solved even after contacting Godaddy.

    I have this same error. However only when I add www in front of my domain. https://sellemental.com produces no error https://www.Sellemental.com does.

    Warning: Class __PHP_Incomplete_Class has no unserializer in /home/content/p3pnexwpnas13_data02/77/3033977/html/wp-content/object-cache.php on line 520

    GoDaddy is claiming it’s not a GD problem but all posts seem to point only them.

    ???

    GD ended up changing my domain to https://www.sellemental.com instead of sellemental.com which eliminated the need to redirect … which fixed the problem.

    Good. If the problem still persists then check out this thread.

    ****** SOLUTION *********

    This fixed the symptom but not the root of the problem, which is something on the Godaddy Managed WordPress side.

    I got this fix after several hours with GD support. As mentioned above there is a problem with the GD caching feature, until they fix it you can do this!

    SOLUTION (for Godaddy Managed WordPress Sites):

    1) FTP into your wp-content folder
    2) rename “object-cache.php” to “object-cache-DISABLED.php”
    3) flush your site cache using the GD menu function at the top of your WP admin CP
    4) get a beer

    The more sites you have to fix, the more beers you will need.
    Happy hacking!

    Been dealing with this for a few days now. What’s funny is every time I call GoDaddy it’s the first they’ve ever heard of this issue, they have no clue what could be causing it, and no clue how to fix it. A little bit odd.

    Perfect, @karlalexander-vqz your workaround seemed to fix the issue. Though does this mean the site is without caching?

    Try checking this blog below. This might help.

    https://oneoveractivemind.blogspot.com/2011/06/php-class-x-has-no-unserializer.html

    The correct way to resolve this issue. For example if your site was testsite.com and when you go to the site and you are getting a similar error to :

    Warning: Class __PHP_Incomplete_Class has no unserializer in /home/content/p3pnexwpnas13_data02/77/3033977/html/wp-content/object-cache.php on line 520

    The resolution would be if you are a Godaddy customer to check gateway.godaddy.com and click on settings for the site with the issue. Under the Domain tab If the site is set to https://www.testsite.com then click on actions and select make testsite.com primary and click on ok .

    Give 5-30 minutes for this to update and this should resolve the issue .

    Today, one of my clients emailed me with the same error message. This thread was very helpful, as they are on GoDaddy WordPress Managed Hosting. I called GoDaddy, and they fixed the problem.
