Sounds like you have a bad plugin or theme. Have you tried:
– deactivating all plugins to see if this resolves the problem. If this works, re-activate the plugins one by one until you find the problematic plugin(s).
– switching to the default theme to rule out any theme-specific problems.
– resetting the plugins folder by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause problems.

The problem is that I can’t log in. Any clue?
Try:
– switching to the default theme automatically 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.
I am too facing same problem .Few days ago server, where this blog is hosted,was upgraded to PHP 5.4 .
