Upgrade to 3.1, lost all admin capability

try:
-deactivating ALL plugins temporarily to narrow down and possibly fix the problem. If the problem goes away, activate them individually (one-by-one) to find the culprit.

If you don’t have access to your admin area, try deactivating them manually via FTP or phpMyAdmin.

-switching to the default theme (“twentyten”) for a moment by renaming your current theme’s folder in wp-content/themes. The idea is to force WordPress to fall back to the default theme to rule out any theme-specific issue.

If you don’t have access to your admin area, then access your server via FTP or SFTP or whatever file management application your host provides.

HI, have a similar problem – running 3.1, network upgrade, with subdomains – setup on root.
I cannot see my network admin area post upgrade, and when I click the link in “Thank you for Updating! Please visit the Update Network page to update all your sites.” I get a message that the page did not re-direct properly.
Plugins disabled.
Any ideas?

Can either of you get to /wp-admin/network/index.php?

Ok…GOT IT!! I deactivated ALL the plugins and everything came back. I followed these instructions:

https://codex.www.ads-software.com/FAQ_Troubleshooting#How_to_deactivate_all_plugins_when_not_able_to_access_the_administrative_menus.3F

All I have to do now is figure out which one (which combination) is the problem.

Thanks guys.

You are welcome. ??

Scottlowe, I have exactly the same problem. What plugin was the problem?

Hmm, I deactivated all plugins using PHPMyAdmin and I still can’t get in… any other suggestions?

Tried the FTP method, but no success.
I can not access /wp-admin/network/index.php? – thought I could but after the FTP job I checked and it won’t accept my password – doesn’t say it is wrong, just no go.
Then I tried to reset the password – page would not redirect – not sure just what is going on.
Still have the problem of no network admin.

@ken. login first. then try to visit that page by typing it in.

Hi Andrea, you are a STAR!
Maybe there was a bit of cache or such not clearing, but the manual type-in worked a treat. – and I thought life was just a “cut and paste” process. Lesson learned.
Again, a big THANK YOU.

In a blink, back again – this may be something to do with my settings, but:
I now can access the network admin by typing in the url /wp-admin/network/index.php?, but I cannot access it by simply clicking on either of the two links at the top of the page
1= “Thank you for Updating! Please visit the Update Network page to update all your sites.”
2= “Network Admin”
I get a re-direct error. Checked cookies settings – Accept 1st party, prompt for 3rd party, accept session cookies, override auto cookie handling.
Clicking the admin link top of the Network page redirects to the non-network admin page /wp-admin every time

Also I am finding redirect failures when I do any of the following:

1. Try to activate a plugin in wp-admin.
2. Try to activate a plugin in wp-admin/network
3. Try to add a new plugin in wp-admin/network

Now here is a puzzle – and maybe a clue??
When I am in wp-admin/network and go to activate a plugin I get the redirect fault, but I then go to wp-admin area and find the plugin activated…..
So back to wp-admin/network, activate another plugin, and then refresh the /network page – viola – the plugin shows as activated for the network.
Sorry to keep bothering you all. It’s a problem of redirects not working it seems.

Ken

Check your plugins. turn them all off if you can. Does the problem persist?

This is partly in response to benjancewicz question with the hope that it helps others. Also, I am leaving out what DID NOT work.

First, these are plugins I had installed:

* Image Slider
* Lightbox 2 (deactivated)
* User Access Manager
* WP-e-Commerce
* Shadowbox
* TinyMCE
* Widget Wrangler
* Cforms II
* Tierra Audio Playlist
* Slideshow Gallery Pro

(1) I used FTP to rename \plugins to \plugins-hold and created a new, empty \plugins folder.

(2) I logged into admin and found the Plugins menu notifying me that the plugins could not be found and were deactived.

(3) While still logged into admin, I used FTP to rename the empty plugins folder to \plugins-sav and renamed \plugins-hold back to \plugins

(4) I refreshed the Plugins admin and everything showed up as Deactivated.

(5) I did a Network Activate of the plugins one by one and, sure enough, on choked! It was Tierra Audio Playlist.

(6) Without logging out I used my (still opened) FTP window and dragged Tierra Audio Playlist into \plugins-sav.

(7) I refreshed the Plugins admin and it came back. The menu gave me the same “not found” error for the Tierra Audio Playlist plugin.

(8) I dragged the plugin back from \plugins-sav to \plugins, refreshed the Plugins admin to find Tierra Audio Playlist back again, but deactived.

(9) I did a proper Delete of Tierra Audio Playlist.

CONCLUSION: As of this posting, Tierra Audio Playlist was only tested up to 3.0.5. If I were to make any recommendation it would be (1) to deactive all plugsin that are not specifically ready for 3.1 and then bring them on-line one-by-one … with an FTP window open (2) and, (benjancewicz and others), I recommend un-doing what ever you did in phpMyAdmin before trying this procedure.

Hope this helps. Good luck everyone.

@andrea. Turned off plugins – had to refresh as previous post to see deactivated.
Still have redirect problem – perhaps I missed a file in the upload of the WP 3.1 files???

@ken – could be. reupload them, make sure there’s a wp-admin/network/ folder with files in there.

And disable every single plugin. even the ones in mu-plugins.
