First your joomla version is unsecure and you must update to the latest version which now is 3.4.8 . Before do that you must back up .
Now for blank page you must put in configuration.php in error reporting maximum to see what error has this blank page or check your error_log file .

Not match above topics with my problems. My Administrator login page showing Blank. In administrator error_log there is no such kind of error.

If you think that there is some modules or plugins that you installed and make this blank page and you remember them, you can find them and rename their folders with ftp to not work.
