I can’t log in to my dashboard after upgrading to 4.7

  • I upgraded to 4.7 and now I can’t access my dashboard. My site seems to be working fine on the front end.

    I cleared my safari cache and it still redirects me to this url:

    https://heatherserody.com/wp-admin/upgrade.php?_wp_http_referer=%2Fwp-admin%2F%3Fv%3D325e709089b0

    …which is a blank page.

    I tried logging in on chrome and I’m getting a http 500 error.

    My site is on a VSP server through Blue host. Customer service wants me to go into my file manager and disable all my plugins that way but I don’t code and have no idea how to do this.

    I asked them to help me revert my site back to version 4.6 but he says that they can’t do that.

    Any help you can give me is very much appreciated.

  • Try:
    – switching to the default theme automatically by renaming your current theme’s folder inside wp-content/themes and adding “-old” to the end of the folder name using FTP or whatever file management application your host provides.

    – resetting the plugins folder by FTP or phpMyAdmin.

    – re-uploading all files & folders – except the wp-content folder and the wp-config.php & root .htaccess files – from a fresh download of WordPress. Make sure that you delete the old copies of files & folder before uploading the new ones.

    – running the upgrade manually via wp-admin/upgrade.php

    I have no idea how to do any of that. I need someone to help me.

    Hi @hserody,

    With your file manager you should be able to browse the files and folders that make up your WordPress website. You will see a file called .htaccess, rename that to .htaccess-old and then try to visit the admin panel again.

    Let me know if that solves it and we can try something else.

    This is a common problem a lot of people have, me included. You need to reinstall a backup that you hopefully have from before your upgrade and that will put you in the position you were in before you upgraded. Then do not upgrade to 4.7 until they release a fix for this serious wordpress bug.

    Thanks Alex and Esmi. I was able to rename the w3 total cache plugin and it allowed me to access the dashboard. Then I tried activating the lpugin again and it caused a fatal error. So then I removed the w3 total cache plugin and 4 caching files. The error went away.

    I tried to redownload the w3 total cache plugin after removing the old files and it failed.

    I now see that w3 total cache is untested with version 4.7 and there are similar problems being reported in their user threads. I still need caching, but don’t want to recreate problems.

    any advice?

    That is interesting, well done solving it by removing W3 total cache. My problem still existed when I disabled W3 total cache or is simply disabling not enough, does it need to be deleted?

    Thanks. The guy at Blue Host walked me through it. I had to delete the plugin and 4 related caching files – I would not have known to delete the 4 related caching files as well – he told me which ones…

    Thank you. Though I understand first hand the incredible stress this issue causes, I wouldn’t desert W3 Total Cache as it is the best caching plugin (I saw on the W3 support site you said you might). Just wait until they issue an updated version that is compatible with the wordpress 4.7 update. For me, I used a backup to downgrade wordpress on my website and I’ll wait for W3 to get themselves sorted before attempting to upgrade again.

    Ok, I think that’s good advice. I’ll give it time and monitor the forums to keep an eye on how things develop. I just hate to see my site speed degrade in the meantime. Thanks!

    I am having the same problem. I just get a blank page when I go to log in on several of my sites. I guess I have to roll all of them back?

    oddly not all of them that have W3 Total Cache are affected.

    Ok I figured something out. If you do not have minify turned on in w3 Total Cache, it seems to work with the 4.7 upgrade.
