404 error after updating to 3.7 (11 posts)

    [Moved from Requests and Feedback]
    Updated to 3.7 from dashboard and site started throwing 'Page not found' while clicking on Themes and Plugins on the dashboard.

    Deactivated and deleted all the plugins via FTP
    Updated to 3.7 again via FTP.
    Still same error.
    Deactivated the theme (Mesocolumn),and instead of reverting to Twenty Thirteen, the site is completely blank though all other functions work properly.

    What should I do next?
    FYI, my site is pakhribas.com, but there's nothing left to see there!

    Do you have a recent backup of your site? If so, delete everything left in your site, do a clean install of WordPress and restore your site.

    No backups, can't install back up plugins either.
    Can I upload a backup plugin via FTP? Will it work?

    I already did a clean install of WordPress via FTP, everything was deleted or overwritten as per this article http://codex.wordpress.org/Updating_WordPress#Manual_Update .

    How should a Clean install be done?

    You had 404 errors 2 weeks ago? Was that resolved before this?

    The media library is there intact with all the tutorial pictures, the posts are there and the pages are there.

    The themes aren't there and the plugins aren't there.

    What would be your best advice for such a situation?

    Try to hard reboot your server/vps and clear cache from CDN service if you are using CDN? Will be useful?

    Most of the good hosting companies maintain backups of sites hosted on their servers. Your host may also have them. Have you tried to contact them for a complete backup, or help with restoring your site? It's worth a try.

    New story has developed.
    Reverted to 3.6.1, the site was alive. Installed MesoColumn 1.5.6 theme again.
    There was a little problem http://wordpress.org/support/topic/catchable-fatal-error-38?replies=32 .

    I installed MesoColumn 1.5.7. The problem was solved. Everything okay, the only plugins installed are Akismet and BackUpWordPress.

    I updated WordPress to 3.7 again through the dashboard. Right after the message that WordPress was updated successfully, would lead me to the dashboard (or somewhere!),a 404 page opened.

    Plugins and Themes aren't lost this time, I can click on them.
    But the theme page has no themes (2012&2013)under Available themes. Only MesoColumn is there. Click on install theme and there's the search box but nothing below Feature Filter.

    When I click on Updates below Home, a 404 page appears.

    What could be causing this? What should I do next?

    I think something weird is going on in your site though you could resolve the issues with WP version 3.6.1

    But the theme page has no themes (2012&2013)under Available themes. Only MesoColumn is there.

    It's strange that the default themes (2012 & 2013) are not under available themes (unless you deleted them). Did you check if the themes are listed in your themes folder in your File Manager/FTP? If not, you might have deleted them and you may need to reinstall them at least for troubleshooting purposes.

    Looks like your current theme MesoColumn is now NOT listed in WP theme repository (please check). And I feel something this theme does (or does not do) may be creating many other problems.

    You may try:
    -deactivate all plugins and switch to one of the default themes and then try to update WordPress
    -if it does NOT work, while keeping the same settings as above, try a manual update.

    Done. But I get the problem which is exactly similar with the issue raised in this thread. http://wordpress.org/support/topic/cant-install-plugins-themes-or-reinstallup-wordpress-get-a-404-page-instead?replies=11#post-4813995
