Cannot update plugins from Admin panel

  • There’s a problem updating plugins and themes using the Update menu item in the admin panel. Apparently no connection is being made to my server, if I interpret the message in the browser correctly (Chrome):
    “No data received
    “Unable to load the webpage because the server sent no data.
    “Reload this webpage
    “Press the reload button to resubmit the data needed to load the page.
    “Error code: ERR_EMPTY_RESPONSE”

    Explorer:
    “This page can’t be displayed
    ?Make sure the web address https://www.MYSITE.com is correct.
    ?Look for the page with your search engine.
    ?Refresh the page in a few minutes.”

    In the address bar is: https://www.MYSITE.com/wp-admin/update-core.php?action=do-theme-upgrade or
    https://www.MYSITE.com/wp-admin/update-core.php?action=do-plugin-upgrade

    The issue occurs with separate installations on the same Web host: GoDaddy, but since this has never been a problem before, I’m stumped.

    Thanks for any help.

    I just did a manual upgrade by replacing all but the wp-content folder and the wp-config file and am facing even more grief. https://www.mysite.wp-admin now gives me a white screen and the homepage gives:

    Warning: require_once(/home/content/html/wp-admin/includes/plugin.php) [function.require-once]: failed to open stream: No such file or directory in /home/content/html/wp-content/plugins/jetpack/modules/theme-tools/random-redirect.php on line 15

    Fatal error: require_once() [function.require]: Failed opening required ‘/home/content/html/wp-admin/includes/plugin.php’ (include_path=’.:/usr/local/php5_3/lib/php’) in /home/content/html/wp-content/plugins/jetpack/modules/theme-tools/random-redirect.php on line 15

    I will now delete all and start from scratch.

    In my case the part of the problem IS jetpack. I renamed the jetpack plugin folder and was able to load the homepage. However, I now get an internal server error (500) when I try to get to the admin page. I’m locked out.

    The temporary fix has been to roll back to 3.92, which is not a fix for 4.0

    I’m having exactly the same problem. I just updated to 4.0. Please share your solution (if any!)

    My “fix” has been to revert to 3.92, capnted. I’m submitting the info with the error message to Jetpack support as we speak.

    Replace all but the wp-content folder and the wp-config.php file. Back up the file so you don’t lose your settings and don’t overwrite your wp-content folder as it has you themes and photo/file uploads.

    Another step towards resolution: On another 4.0 installation with the same issue, I went to the plugins page (/wp-admin/plugins.php) and clicked on the Update Now link there and the update proceeded fine, similarly with the theme. From /wp-admin/themes.php I clicked the link /wp-admin/update.php?action=upgrade-theme&theme=responsive&_wpnonce=813d33009c and the update proceeded.

    However, trying to update from /wp-admin/update-core.php resulted in the messages in the original post in this thread.

    Having a very similar but more extensive issues after upgrading to 4.0 on a Local installation.

    I’m getting this issue when trying to Update plugins but also when:
    – trying to reactivate both third party and custom plugins that previously worked; most of them were even fine after the upgrade but eventually broke
    – When trying to reactivate a custom theme that I had temporarily disabled for debugging purposes

    I’ll let you know if I find anything out.
