Ajax issues on WordPress
You need to cross check each and every path configured in Administer -&gt; System Settings -&gt; Resource URLs. Set them as per your site configurations.


CiviCRM Resource URL : is the URL path to your civicrm directory - Eg http://example.org/wp-content/plugins/civicrm/civicrm
Image Upload URL: is the URL path where your image will be stored. Eg http://example.org/wp-content/plugins/files/civicrm/persist/contribute
Extension Resource URL: is the URL path of the extensions used in your site.


Navigate to Administer -&gt; System Settings -&gt; Directories and set the path as per your needs.


Image Directory: should be the same path as above(Image Upload URL) without the URL part. Eg /var/www/site-name/wp-content/plugins/files/civicrm/persist/contribute
Extensions Directory: same path as set for extensions in the resource URL(without the URL part). Eg /var/www/site-name/path/to/extensions/


Similarly, set all the paths and check if it fixes your site display.
