Unable To Access Admin Or Blank White Page After Install Or Update

42 views 19 décembre 2017 admin 1

After installing a new theme, or updating a theme, your site may return a blank white page or keep you from accessing the admin area.

There are three primary causes for white screens:

  1. Fatal errors in the code that keep the page from loading
  2. Missing or corrupt files
  3. Memory issues with WordPress due to server configuration or database capacity

 

General Troubleshooting – Fatal error

To find out whether the cause is the theme, a plugin, WordPress or your server:

  1. Log into your site via FTP. If you are unsure of how to use FTP, contact your host for assistance.
  2. Under wp-content, go to themes and rename your theme’s folder. For example, manual-off.
  3. You must have at least one default theme in the themes folder for this to work. WordPress will automatically activate TwentyFourteen if available.
  4. Return to your WordPress admin and see if access is restored.
  5. If yes, reinstall and reactivate your theme using a fresh download of the latest version.
  6. If no, the issue is likely not your theme and likely has to do with WordPress or your server configuration.

 

General Troubleshooting – Corrupt Files In WordPress

  1. Download a fresh copy of the latest version of WordPress from wordpress.org and unzip the wordpress folder it contains to your desktop or an easy-to-find location.
  2. Connect to your site via FTP and upload the contents of the unzipped wordpress folder to your site root and overwrite the existing.
  3. When the transfer/overwrite is complete, attempt to access your admin again (it should work now).

 

General Troubleshooting – Suspected Memory Issues

Try increasing the allowed memory in your php.ini to 64M or higher. You may need your host to do this for you.
