https://example.com/blog" - A portion of the website (for example, the Blog section) is using a separately installed WordPress script
- The WordPress script has a heavily customized .htaccess file that contains entries from security and performance plugins such as Wordfence, W3 Total Cache or All In One WP Security
- The connection from the main website script to the WordPress script is being refused due to the configurations of the security and performance plugins in WordPress.
- Cause
- The connection from the main website script to the WordPress script is being refused due to the configurations of the security and performance plugins in WordPress, which can be seen within the .htaccess file of the WordPress script.
Resolution
Review and adjust the settings of the plugins on the side of the WordPress script in order to allow the connection from the main website to the WordPress portion of it.
Alternatively, you may disable the necessary plugins on the side of WordPress plugins entirely.
