Hi @FascinantJapon, hi All!
Your solution works also with WP 2.8.4 PL (Polish) :) Thank you for sharing!

This plugin is my very first I install on new website.

So, let's donate few beers to Filosofo :D (I will if I only have money). Cheers!

Thanks @FascinantJapon, it works in WP 2.7.1

After posting the above post on the French forums, their a slight difference which is that the fr_FR.php must be EXACTLY like:
<?php
$wp_default_secret_key = 'put your unique phrase here';
?>

i.e. the key MUST BE 'put your unique phrase here'.

Here is what I did to make it work. I use a French version, so if you use another language version, adapt the language file name to your situation.

1. get the files wp/wp-config.php and wp/wp-content/languages/fr_FR.php (adapt the files path to your needs)
2. Go to the following address: http://api.wordpress.org/secret-key/1.1/ and copy the 4 keys that are generated
3. Paste the 4 keys in wp-config.php as shown in the picture below:

4. Open the fr_FR.php file and fill the key with one of the 4 keys already generated or another one:
http://friefrench.free.fr/stuff/cle-francais.jpg
5. Reload the 2 files on the server

That's it. Now all functionnalities from the backup works: mail, schedule, etc... Also, I had the same problem with the plugin "Wordbook" and that makes it work too. Probably some others I don't use too.

PS: And a great thanks to filosofo for this plugin critical to any WP installation!

Hi,
I have found the problem, is a jquery conflict with javascript in admin menu area.
But i can't solve :(

Hi,

In Wordpress Spanish version installation also gives the same bug.

I have tried to find by myself, but since I dont know PHP, it's a little bit hard...

I managed to find that the error message is issued by the "user_can_access_admin_page" php function in plugin.php file. The bug disappears when the file "wp-de-backup.php" is deleted. It's not a file permission problem..

It seems that something goes wrong when the plugin registers itself.

Hi, I'm french too, and have this very same problem on the french version of my blog. But oddly, the plugin works well on the english version!

There are two different installations of wordpress 2.7. They were done at the same time, with the same ftp client. The installed plugins are the same, etc.

I was suspecting an error in file transfer (I already have that with filezilla), so I removed the plugin and transfered it again, with same results.

I was not able to spot a difference between the two installations.

I'll be glad to do some investigations under your direction. Just email me at rvbf "ampersand" wanadoo.fr

Thanks

Same problem:
"Vous n’avez pas les droits suffisants pour accéder à cette page."
"You don't have sufficient rights to access this page".
As I'm french, I will take a look at the solution given here.

Well apparently, I'm not the only one with this problem : http://www.wordpress-fr.net/support/sujet-19916-maj-connexion-admin-devenue-impossible
this link is in French but it's just to prove my point ;)

There is a known bug in /wp-content/FR.php which redefines the variable $wp_default_secret_key which is apparently crucial for identification.

I just got rid of the file and it now works...thank god it's not an important file ^^

Thanks anyway ;)

That's odd. It would help if you could give me the exact error message or let me see the problem in action.

Hello,
I updated to version 2.7 of WP today, and could not log into the admin.

I upgraded to the latest version of the plugin (2.2.2), but i still have the same problem.

The only solution is to delete the plugin files from my ftp, otherwise I just can't connect.

The error message is "you don't have permission to access this file" or something like that.

Any pointers on what could be the cause of that, and how to fix it?

Thanks in advance ;)
