Support » Fixing WordPress » Getting this message “Fatal error…”

  • Hey y’all! My friend’s website, TheFullQuiver.com, is having issues! Whenever I try to go to the site (logged out and in) I get this message, “Fatal error: Unknown: Cannot use output buffering in output buffering display handlers in Unknown on line 0”
    What could be the matter? I find that on some browsers it works when I refresh the page. But I can not put any of my products in the cart or view the “Links” page. I’m thinking it may have something to do with hosting but I really don’t even really know where to begin.
    Thank you for your help in advance! 🙂

  • It looks up to me. Did you resolve this?

    I’m seeing your error and sometimes after refreshing your site shows up.
    Perhaps its a plugin conflict? A caching plugin maybe.

    Yes, our caching plugin is disabled. Maybe it’s a plugin conflict??? How would I determine if it is a plugin conflict?

    …and @kmessinger, I do still see the error. It is not resolved yet. It’s weird because sometimes it works and sometimes it doesn’t. I’ve found that the browser you use is also a factor.

    Hi downhomeme,

    It’s basically a trial and error approach to single out which plugin is conflicting with another.
    Disabling them one at a time and refreshing the site to pinpoint the culprit has been my approach.

    Caching plugins sometimes leave behind cached folders you might have to remove manually via FTP.

    Let me know,

    So to first things first… to delete all the caching folders could I just go to my installed plugins list and DELETE W3 Total Cache (to remove all the files)?

    By the way… THANK YOU so much for your help and support!

    No problem!

    That would delete the plugin yes if you no longer want it. I would delete it through the plugins page via WordPress admin.
    Then inside wp-content, wp-content/plugins check for any named folder with cache or W3. I can’t remember the actual names of the folders off the top of my head.

    Side note.

    Your navigation is being block by your main content. Consider putting a z-index on your #topmenu.

    
    #topmenu {
        text-align: center;
        position: relative;
        bottom: 125px;
        z-index: 99;
    }

    Alrighty there… Went and deleted the W3 in the WP dashboard… Went in my files (through my host) and I don’t see anything having to do with caching. So this step should be done. So next… Going through each one of the bazillion plugins I have… Just out of curiousity… Why do you think it has something to do with a plugin?
    Thanks.

    So that is the first step in troubleshooting these kinds of things is determining if it is a plugin causing the issue.

    I have seen that error before and the cause was a caching plugin conflicting with another plugin for whatever reason. I could be wrong as well!

    If you do have a bazillion plugins (ha) that could be the problem so start by deactivating one at a time and refresh and see if the error goes away or doesn’t appear. Again, kinda trial and error.

    Did the z-index. Thanks for pointing that out.

    Ok!!! It was the Social Media Auto Publish plugin. Thankfully, it was one of the first ones I deactivated!! So now the website is going good from the outside (when you’re not logged in). But I still get the error when I am logged in… but that’s not a huge deal because now other people can purchase CDs, look at the website, etc. THANK YOU!

    Nice! Well keep checking when you have time, there might be a plugin causing admin issues. Also update any that need to be and its good practice to remove any deactivated plugins if you won’t be using them.
