Post Preview and editor not working

    Since the upgrade to 2.8.4, I have not been able to use the HTML editor instead of the visual editor, and the Preview Post button no longer works.

    When loading the page, I get 2 javascript errors: “jQuery is undefined” and “edButtons is undefined”. When clicking on the HTML tab for the editor, I get the following Javascript error: “switchEditors is undefined”. When I click on Preview Post, nothing happens at all.

    Also, the “More” tags used for creating teasers cannot be created or deleted.

    It seems something might have been deleted or left out during the upgrade. Any ideas?

    Thanks.

    Ok, so I found a [temporary] fix. at this website: https://www.ads-software.com/support/topic/279132?replies=90 I found a fix that worked for me. As it states below, though, it makes Admin run slightly slow.

    6. Add define( ‘CONCATENATE_SCRIPTS’, false ); near the top of wp-config.php. That would make WordPress admin run slower, so you can try removing it in a few days and testing again (this would eliminate any stale network cache)

    Does anyone have any idea what causes this problem and how to avoid it happening again? Does anyone even read this forum any more anyway…?

    I found the issue to be because two JavaScript files had failed to upload and were 0 kb in size.

    Uploading the following files again worked for me…

    wp-includes/js/jquery/jquery.js
    wp-includes/js/jquery/jquery.schedule.js

    Hope this helps others having similar issues.

    M.
