Apple announced the dates for its Worldwide Developers Conference on Wednesday, but developers got a surprise when they tried to renew subscriptions — Apple’s Safari Web browser wouldn’t complete the transaction. One developer that ran into the problem sent a screenshot of the chat he had with Apple about the problem. The Apple rep acknowledged the issue and said it was best to use Firefox to complete the transaction.

Not the best start to a developer conference. It is worth noting that not all developers had this issue. As the screenshot clearly shows, this developer’s browser is not upgraded to the latest version of Safari, which is 4.0.5.

Update: Clarified that the developer was renewing his dev subscriptions 10:54 am PT
