im having the same issue
i just upgraded to the latest version (through my cpanel/fantastico) and last night after upgrading it still worked
now im checking and it just turns up blank
not loading anything
its php_memory_limit option, turn of some plugins (delete them using FTP) and then you can:
increase your memory_limit by editing .htaccess file
or ask your webhosting provider about increasing memory_limit for your account by editing php.ini file, you can edit it personaly if you have your own server
just ask google about details of both metods.
