A recent security update to Internet Explorer has changed the way it deals with secure sites like meccparts.com and other e-commerce sites.
Users may experience errors when processing orders or registering for new accounts.
Microsoft has acknowledged the problem and has released a patch that addresses part of the problem but our testing indicates that many users will still have problems.
Until this problem is completely resolved Internet Explorer users need to be aware that they may experience "Page Not Found" errors when confirming an order. Selecting Back or Refresh in an attempt to get around this error may result in multiple orders being sent.
Please be assured that we will only process one order and will not process duplicate orders unless we receive specific instructions from you.
In the meantime you may want to switch to a standards-compliant web browser as an alternative to Internet Explorer. We recommend Mozilla Firefox.
