Can't Get Thumbnails to Generate

  • I’ve tried this on 2 websites, hosted on 2 separate dedicated servers. One was an existing website, the other brand new WP installation with default 2016 theme.

    On both cases, the thumbnail doesn’t generate. Creating my own thumbnail with an image editing program and uploading it to the library, then setting it as thumbnail works. Likewise, if I don’t set a thumbnail, a default thumbnail is shown. So that part also works.

    What doesn’t work is generation of the thumbnail by the plugin. Whether I choose to generate 1st frame, randomize, or choose from the video, I get the preview, but generation will ultimately result in a blank image (white rectangle).

    What am I doing wrong? How do I get the plugin to generate thumbnails automatically?

    It sounds like there’s something blocking the thumbnail saving process. The thumbnail is actually created in your browser then uploaded to the server. The problem is most likely in your server configuration and not in your WordPress setup. When you save the thumbnail you probably get an error in your browser’s developer console. Try making a thumbnail for a very low-resolution video. If you don’t have one, use this low-res version of Big Buck Bunny. If that works when the higher resolution thumbnails don’t, then try increasing the post_max_size and upload_max_filesize settings in your php.ini or if mod_security is enabled, increasse SecRequestBodyLimit or SecRequestBodyNoFilesLimit in modsecurity.conf.

    Also, if you have FFMPEG installed on your server, you can try disabling in-browser thumbnail creation on the FFMPEG settings tab of the plugin settings page.

    i also had this problem.

    did you try changing the uploads folder permission to 755

    where we can control number of the thumb generation, i set 1 but it always creating 2, what im doin wrong?
    thanks

    @yamiraan please start a separate post for your separate problem, and explain exactly where you’re setting the number of thumbnails. There are many ways that can be done and I need to know specifics.
