Problem Description:

Example:

Fatal error: Cannot redeclare _verifyactivate_widget() (previously declared in /themes/the-writer/functions.php:40) in /home/yoursite/public_html/wp-content/themes/the-writer/ocmx/includes/functions.php on line 102

This error is likely due to one of the following:

  1. Incorrectly setup child theme
  2. Theme update failure or update skipped (unsynched files)
  3. Incomplete theme upload
  4. Botched WordPress install or update

Answer:

All solutions require you to have FTP access to your site either through a free program such as FileZilla, or your hosting control panel.

Regain Access to Your Admin

  1. Connect to your server via FTP go to wp-content/themes
  2. Rename your active theme’s folder to anything else. Example: store-off
  3. This requires at least one default theme in the themes folder, as WordPress will automatically attempt to activate TwentyFourteen
  4. Attempt to access your admin
  5. Go to wp-content. Rename the plugins folder to plugins-off. This forces all plugins to deactivate.
  6. Attempt to access your admin.
  7. If this worked, you have a conflicting plugin. Proceed to activate and setup your theme without plugins activated, then reactivate them.
  8. If this did not work, resintall WordPress.  See Unable to access admin or blank white page after install or update
