Walking through Joomla forum there's some guys got blank home pages on the fronted or backed admin page.many people ask why they got these errors, and how to solve this.  well, there could be many other reasons,but, to give you something to try, maybe you could look into these points.
joomla blank pages Occurred:

  • after login (admin or frontend)
  • after installation,fresh install joomla or some extensions
  • after transfer, migration,or upgrade

Reasons cause blank pages and the solutions:

1.Joomla original files get corrupted

Sometimes, joomla original files get corrupted, overwritten, so, to solve this, simply locate your version of joomla on joomla downloads page and download the original full joomla package. You can then login to your FTP and re-upload all content there and overwrite any existing file. If you are using any original template and you have made changes, this might alter your template. So, make sure you have a full backup. This won’t affect your existing articles as it doesn’t modify anything in the database.

2.You have migrated your joomla from one server to another

A reason could be that your new server not meet joomla minimum technical requirements.To solve this,you musy make sure your hosting meet the requirements.
Another reason could be that you have migrated your joomla from one server to another. Sometimes, different servers have different root directory structures. So, your plugins might not be pointing to correct directory. So, to solve this, look into your plugins and make sure the configuration files point to correct paths for all the plugins resources.

3.PHP error from any extensions

Another reason could be any PHP error from any modules or plugins, to solve this, you can enable the debugging mode from the global configuration. This will show you the error message (in case there is any) instead of the white page only. You can then analyse the error message and act accordingly.

The steps:
The way to find out what the error is, is to enable error reporting within Joomla! which you can do in Site->Global Configuration->server->error reporting. Set it to either simple or maximum.Load you page up again, and see if an error is shown.If you still get a blank page, then we to get a little more aggressive,Edit your /index.php (in the root of your Joomla! install),and add the following somewhere near the top, within the <?php tag ,

error_reporting(E_ALL | E_STRICT);
ini_set("display_errors", 1);

The sadly, the above wil not report parse errors. So if you are still getting a blank page, you need to find out if you have access to error_log which many hosts give these days. If you are unsure, ask your hosting provider for access to your apache error_log file.
Alternatively you can edit your /.htaccess file (create it if it doesnt exist)and enter

php_value display_errors 1
php_value display_startup_errors 1

Provided your host supports user htaccess files, this will show any error your site is generating.Once you have your error, you can start to figure out why its happening.
