Error upgrading from WordPress 3.6 to 3.6.1

Try manually re-uploading all files and folders EXCEPT the wp-config.php file and the /wp-content/ directory from a fresh download of WordPress. Make sure that you delete the old copies of files & folder before uploading the new ones. Read the Manual Update directions first!

Thanks for that advice. However, I have already tried that.

Have you also tried:

-deactivating ALL plugins temporarily to see if this resolves the problem. If this works, re-activate them individually (one-by-one) to find the problematic plugin(s). If you can’t get into your admin dashboard, try deactivating via FTP or SFTP or whatever file management application your host provides. If applicible, also remember to deactivate any plugins in the mu-plugins folder. The easiest way is to rename that folder to mu-plugins-old.
– To rule out any theme-specific issue, try switching to the unedited default theme for a moment using the WP dashboard. If you don’t have access to your admin area, you can switch to the default theme by renaming your current theme’s folder in wp-content/themes and adding “-old” to the end of the folder name using via FTP or SFTP or whatever file management application your host provides. Alternately, you can remove other themes except the default theme. That will force your site to use it.
– resetting the plugins folder by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause problems (because the hooks remain unless plugins completely removed or some plugins stick around in cached files. So by renaming the folder, you break them and force them inactive).

Thanks for the reply. I actually did try each of those. After I read your post, I tried all of them again; still not successful.

– Try flushing any caching plugins you might be running, as well as server and/or browser caches. Also, try different computer/different browser.

-If no joy, you may want to contact your hosting provider and discuss the problem with them as well.

I tried flushing W3TC; it would have been disabled anyway while the plugins folder was moved/disabled.

I’m running my own VPS, so there’s not much that my hosting company will do for me.

Thanks for trying. I do appreciate it.

The WP version is retrieved from version.php. That’s it. When you browse your new installation, that version is saying 3.6.1?
You could also export your XML file, backup your widgets (using Steven Gliebe’s Widget Importer & Exporter), backup your db, backup your entire website, delete the db, and run the install from the start. After it, you can import your xml and widgets. Obviously, dont touch the wp-content to preserve your uploads. Did you tried this? ??

Yes, I tried this too. I really tried (seemingly) everything, which is why I turned to the forums. I am imagining that the next release (3.6.2?) might resolve this. Thanks for the reply.

Quite strange issue. You better do a complete backup, and start doing daily backups if you update your website regularly. Said this, then you can wait for 3.6.2 to come.
I’m intrigued, let us know if 3.6.2 solve this.

Hey,

Try flushing out (drop/remove) _site_transient_update_core under the option table.

Thanks

@marcelo Pedra: I have daily backups running, thank you for your reply.

@anshu Verma: I just tried that, and the post-update screen stil says “Welcome to WordPress 3.6.” Thanks for the idea.

Try:
– switching to the default theme 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

@esmi: I have already been down that road, and it did not solve the issue. Thanks.
[BTW: I’m using nginx so .htaccess does not apply ?? ]

@kevin: did you tried upgrading WordPress with all the plugins deactivated?

@kevin: is your WP install using default english or another locale? what about changing the locale of WP and download the update to another language, i.e. spanish?
The WP packages use to be different between locales. After that, you will be able to reinstall automatically the same language or the original english one ??
