We're celebrating Europe this week and we'd like to support all of our European Union customers by covering the VAT rate. Discount is valid for all new purchases and manual renewals and applies automatically during checkout.
When I enable the Presentation page, I regularly get a ‘Page Not Found’ on the homepage, in all browsers that I use for testing (MSIE, Chrome, Firefox).
Refreshing the page or clearing the browser cache does not help, disabling/re-enabling the Presentation page does.
Try disabling all plugins and see if it works then. Also, make sure that under WordPress >> Settings >> Reading you have “Front page displays” set to “Your latest posts”.
