Couldnt Update WordPress 2.2.1 to 2.5.1

On your first link I get the message

No Upgrade Required
Your WordPress database is already up-to-date!

so go quickly and finish the upgrade process.

I have exactly same problem. Help please

In that case you do NOT have any problem… because the OP (=original poster) doesn’t have a problem either. WP is installed and upgraded on his blog.
Stop posting about the same in different topics – I tend to delete duplicate posts.

Sorry, now its working fine because i do a roll back to the version 2.2.1

whe i try to update i have no post pending, plugins disabled, and the theme was the original.

Moshu, please dont close this issue. Thanks in advance.

Be interesting to know how you are getting visitors to https://www.radians.com.ar redirected to https://www.radians.com.ar/blog ?

its a simple redirect file. I have in that way in other wordpress blog, and i could update without problems.

Here in radians i dont know why it fails.

thanks for your help. Robert.

Backup your database, check/rebuild your database tables.

Deactivate all plugins. Logout, clear browser cache.

Delete and reupload files as described in Steps 7 and 8 in Upgarding WordPress Extended.

Do the upgrade.php

Upgrade the plugins

Activate plugins

Also,

Another method (without the redirect) to make WordPress available at https://www.radians.com.ar In Settings->General, change the Blog address (URL) to https://www.radians.com.ar and put this index.php file in your web-root folder (it is the same folder that contains the blog folder)

<?php
/* Short and sweet */
define('WP_USE_THEMES', true);
require('./blog/wp-blog-header.php');
?>

Then update your permalinks in Settings->Permalinks.

wow, its a good tip.

Could this cause the problem with the migration? in the other blog i have a similar redirect and the upgrade process works fine.

Really i dont know how to solve it.

Thanks for your help. Robert.

i could resolve it by my own.
