    Hello friends!

    I am using elementor (free) for my website and I am thankful for that.
    I have a problem with edit with elementor, when W3 Total Cache plugin is active. for last two week, when I edit a post/page, is deactivate the plugin and edit. But usually, I forget to reactivate the plugin thus my load time is increased.

    The error I get when W3TC is activated is:
    Fatal error: Unknown: Cannot use output buffering in output buffering display handlers in Unknown on line 0.

    I have also disabled the caching for logged in user in W3TC plugin setting, it didn’t help.

    Thanks to the forum and plugin author in advance.

  • You probably already did this but did the Compatibility Check go through without any issues?

    Thanks for your response @lestexas60

    Inside the page cache, I enabled compatibility mode but it didn’t work for me.

    I ran the compatibility check test (inside general setting), I got the following response, which I literally don’t understand, what does it mean.

    I don’t know if this would affect it but most Hosts are up to PHP7 or 7.2
    This is suppose to improve the loading speed of your site and other enhancements.
    If you have CPanel at your Host, you should be able to upgrade yourself. Make sure your running a reasonably current WP and Elementor too.

    I have already updated WordPress and elementor. I don’t know much about PHP upgradation. The problem persists, the edit function only works if I disable the W3TC.

    Hi!!

    I have the same problem with Fatal error: Unknown: Cannot use output buffering in output buffering display handlers in Unknown on line 0.
    It happens when I try to Edit with Elementor pages that are already created.

    And when creating a new one, came the pop-up of Learn More. I deactivated Booking.com Banner Creator plugin, and then I could create a new page (didn′t add any content to it). But on other pages the pop-up keeps coming.

    What should I do?

    Hi!!

    I just deactivated the Fast Velocity Minify and could edit the page I was trying to edit. But not other pages…. Please help!!

    Right now, I have updated the PHP version from 5.6 as said by @lestaxas60 and my problem is solved. I can edit any post while W3TC plugin is active.

    Thank @patuantunes and @lestaxas60 , I am glad you people helped.

    I had the same problem with Elementor, but I updated my PHP version via cPanel to version 7.0 as mentioned above and it fixed the issue. Thank you guys!

    Hey yall sorry i am late to the party.
    The fix for this is to turn off advanced disk cache in the w3TC plug in. Your PHP set up does not support it and not many hosts do.
    The modules not turned on that w3tc needs are listed below.
    Most of php 7.2 does not use these ancient functions hence why the plug in seems to work better on 7.2
