When an update is published to your website, it is possible that a person using the website might get an error when they access a page. This is a temporary issue caused by the browser caching old references to the website. There is nothing wrong with the website. Our server validates the data sent from each page as a security measure and if it receives data cached from a prior update to the website it will generate a "ViewState" error.
The problem is usually remedied by one of these steps:
- Click the "Refresh" button on your browser.
- Exit all copies of your browser and try again.
- Re-boot your machine and try again.
- Try a different browser. Each browser has an independent cache, which is eventually purged of old data.
