[ghanchi2000]

Recently i upgrade WordPress to 2.7 after upgrade i visit home page its shows blank page after i try to login in admin panel adding /wp-admin in link its work perfectly after i login i try all admin panel all things (include Plugin, Themes Preview and all admin panel) work perfectly but Main Page show blank Page and other topics, categories direct link works fine.

I do one mistake before upgrade i forgot to disable/inactive themes and plugins

Do you have PHP Errors enabled/being displayed?

Try adding

define('WP_DEBUG', true);

to your wp-config.php file temporarily to see if that lets any errors show up.

Another possibility is, do you have a 'index.php' file in your plugins directory (ie. wp-content/plugins/index.php) - I have a feeling it can be caused by that..

Agree. Sounds like a theme error.

More information is needed to continue, lowered priority until new information is available.

No information, sending to next version.

Replying to DD32:

Actually it should be something like this:

@ini_set('display_errors', 1);
define('WP_DEBUG', true);

As many hosters suppress error output for the sake of security.

I had a similar problem. Error output made little to no sense, and it wasn't until I stumbled upon the solution that I really had any clue what might work.

The problem was that I had a high number of "posts to display" set on my "Reading" settings page (was 9999, now 999). I wrote this up at  my blog (links directly to appropriate entry) if you're interested.

My theme sets the number of posts to display (to 9) and, as I mentioned, this worked fine in 2.6. I think this may indicate that there are some performance issues with 2.7 that might be fixable.

Closing this one off before it stagnates. No feedback, etc..
