Blank screen upon accessing Dashboard

Hi,

Try following suggestions:

1) Memory exhaustion

Memory exhaustion is one of the most common reason behind white screen of death error. To fix this, you will need to increase the memory limit in WordPress. Open wp-config.php file located under WordPress directory, add following line in wp-config.php and save the file.

define('WP_MEMORY_LIMIT', '128M');

If you still get this error after above fix, you will have to extend the PHP memory limit from php.ini file. You can also contact your web host to increase the PHP Memory limit.

2) Try Deactivate All Plugins Through cPanel

Login at cPanel, Under Files section, Go to File Manager.
Select Web Root (public_html/www) and click Go.

Expand the public_html folder, and navigate to the /wp-content/plugins folder.

Right click on the /wp-content/plugins folder and rename it like plugins.old. This will deactivate all of the plugins at once.

Now, reactivate plugins folder again by renaming back to plugins. This will allow you to access the WordPress Dashboard again.

If white screen disappears from your website, activate plugins one by one until the white screen comes back. When it does, you’ll know the culprit plugin.

3) Switch to Default WordPress Theme

If the plugin disabling doesn’t work for you, switch back to default twenty fifteen theme. Access to WordPress directory either through cPanel or FTP, Navigate to wp-content/themes, locate the theme folder you are using and rename it.

WordPress will automatically fall back to the default theme.

4) Troubleshooting with WP_DEBUG

WP_DEBUG is the handy way to determine the problem with your WordPress website. When debugging mode is turned on, you will have list of errors and warnings. To turn on WP_DEBUG in local WordPress website, just add the following line of code to your wp-config.php file.

define( 'WP_DEBUG', true );

Hope that helps.
Thanks,

Hey, thanks a lot.

1. I have been trying the renaming or deactivating the plugins from cPanel. But it tells me Permission Denied. Now I am accessing cPanel from the ID and pswd provided to me by the web host. So I don’t know why permission denied.

2. Where can I find the wp-config.php file?

Ok it’s solved. I just called up the web hosting providers. The guy asked me to do one thing and it fixed a dozen problems.

He told me to go to File Lock and Unlock it. I did that and then I was able to remove/delete plugins from cPanel. I renamed a plugin and ow I can install new plugins as well.

Hell, I have been slogging it out from past 7 hrs, if only I would have called them up in the first place!

Hi,

You should have follwing permissions to your WordPress directory.

public_html == 750
Any subfolder under public_html == 755
Any files under public_html == 644

You can change the permissions from cPanel file manager itself.You can also ask your web hosting provider for the necessary permissions.

Where can I find the wp-config.php file?

You will find wp-config file in your WordPress directory.

Thanks,

These permissions were already in place. But the FileLock was not letting me make any changes despite the appropriate permissions.
