    Is this in list or grid view? Is it faster if you switch to the other view?

    Also do you mostly have images being viewed or is it other types such as videos?

    I have some ideas as to what might be wrong, but I’ll need your help tracking it down if you’re up for it. 🙂

    Well you’re right, it needs some details.
    Both views are slow. It took so long time to load that I can’t tell you which is the slower. But I think the grid view load some media sooner than the the list view.
    Most of the medias are pictures. We have one video, a .zip and a .pdf
    And the library is not so large, about 264 items.

    And you can have all the help I can give you !

    Can you try adding the following code to your theme’s functions.php file?

    If that fixes the issue, then try deleting one of the three remove_ lines at a time to see which of the three is actually fixing the issue.


    The following one resolve the issue:
    remove_filter( 'media_row_actions', array( RegenerateThumbnails(), 'add_regenerate_link_to_media_list_view' ), 10 );

    This issue only occurs for me on PHP v7.2 but it works fine on PHP v7.1.

    Commenting out this line of code solved the issue in PHP v7.2 at line regenerate-thumbnails.php#140

    add_filter( 'attachment_fields_to_edit', array( $this, 'add_button_to_edit_media_modal_fields_area' ), 99, 2 );

    Hmm, I upgraded my local development environment to PHP 7.2.0 and tried to reproduce this but I can’t.

    I dont’t think it’s related to the version of PHP. For my part, I get the issue with PHP 5.4

    I agree with @sugardaddy, I tried to reproduce to one of my other projects which is also running under PHP 7.2 and I can’t reproduce it there.

    Let me expand on my issue,

    So whenever I open Media Library it just freezes there, upon investigation it was filling up my server /tmp folder with gigabytes of data, actually taking full space of /tmp folder which is 6GB. But it doesn’t stop there it continues to put the process in queue I guess, which causes my server to freeze unless I forcefully restart my PHP-FPM service.
    I tried disabling all the plugins except Renegerate Thumbnails and switched to default Twenty Seventeen theme this issue still persists. So not a plugin conflict or theme issue.

    My LEMP setup:
    I have also tested without Xdebug, issue persists..

    Thanks @rahilwazir! That gave me an idea. Can you guys try this version of the plugin to see if it solves the issue?

    Sorry for being so long to answer.
    I upgraded to 3.0.1 and it doesn’t do anything.
    I used your file and it’s ok to me.

    Excellent. Thanks for testing. The fix will be included in the next release.

    Thanks to you ! Great support !
