  • Just tried re-installing one of my sites using the backup buddy install and what ever is causing the problem has not been resolved. The admin page is still not loading.

    This is important as I currently manage about 20 WordPress websites for clients and cannot upgrade them to Version 3.4.1 until this is resolved. Any help would be appreciated.

    thanks,

    I have not had that problem. What version were you upgrading from, just 3.4 or something else? I would try the basics of temporarily going to a default theme (Twenty Eleven) and also deactivating your plugins. Try to narrow down if the error is within the theme or a particular plugin. You also might want to consider turning debug mode on in your wp-config.php file to see if it will tell you the error. http://codex.wordpress.org/Editing_wp-config.php#Debug Good Luck!

    Hi,

    Try the upgrade manually.

    1. Make a backup of the current website
    2. Download WordPress
    3. Extract it
    4. Delete from live website: wp-admin directory, wp-includes directory and all WordPress files from the root apart from wp-config.php and wp-content folder.
    5. Upload the new WordPress version you downloaded.

    This should do the trick

    Johnb81 – did all that using Backupbuddy.
    removed all plugins and determined they were not the problem.

    Thanks though for suggestions.

    Ok,
    so I just deleted everything as suggested by Johnb81 and uploaded all the files from version 3.4.1 – no effect – I think the database is corrupted.

    Is there anyway to revert to version 3.3.2? I have a copy of it as well and had no problems with it.

    This is actually mmconsulting – they somehow messed up my username password here.

    Anyway – I started looking at files in the WordPress setup. I found this code in a number of files and wonder if it some kind of virus or malware.

    Does anybody recognize this?
    thanks

    Yes seems to be malware. As a start get your website scanned by Sucuri; http://sucuri.net/

    Then refer to http://codex.wordpress.org/FAQ_My_site_was_hacked

    Let me know if you have further queries or need assistance with the clean up.

    I recently switched my primary / secondary domains. WP was originally installed on the primary. It has been relocated to the secondary domain. Everything seemed to be fine re:configurations, etc. until I updated a plugin last week that never re-activated. I logged out, and had not attempted to log in again until yesterday.

    Now, when I try to login or logout (site login is required and use a plugin for that), or access the admin panel, I get this error message:

    Server error
    The website encountered an error while retrieving http://lmsobackstage.org/wp-admin/. It may be down for maintenance or configured incorrectly.
    Here are some suggestions:
    Reload this webpage later.
    HTTP Error 500 (Internal Server Error): An unexpected condition was encountered while the server was attempting to fulfill the request.

    I then hit the refresh button, and okay – I’m logged in or logged out as requested. But that is as far as I’m getting

    I used the suggested Sucuri scanning and everything checked out okay.

    I ran a tracert command and ran into asterisks on lines 15-30, so initially believed there was a problem on another server somewhere during the connection process. However 12 hours later and it hasn’t been resolved.

    Looked at the error log file on the server and the error reported relates to that plugin that never reactivated.

    How do I get rid of the plugin when I can’t access the admin panel?

    Is it “safe” to simply delete the plugin files off the server via the file admin section, or should it be done only through the WP admin interface? If the latter – what do I do when I can’t access it?

    Thanks in advance for any feedback.

    I was able to resolve the issue in this manner.
    Once I realized that there was some form of malware in the files (almost all the php files were infected.) I used a full backup I had saved using Backupbuddy from before.
    I unzipped the files. I checked them for the malware but there was nothing there.
    I completely deleted every WP file in the folder using FTP and uploaded the older files instead. This time I did not use the Importbuddy.php or use the Backupbuddy database backup to create a new database.(This is the recommended procedure but it failed to work when I first used it.)
    It seems the database was not corrupted, just the WordPress files.

    After replacing all the files I went to the site and the admin page was working and everything is fine. I did this with 2 sites. As it turns our the original Backupbuddy files I had saved do not use WP Version 3.4.1 but 3.2.2.
    I don’t know if there is problem with Version 3.4.1 but for now I will not upgrade.
    Thanks to everyone who helped.
