I am using the latest Parity client on Mac connected via WiFi (ping 25ms) on the Ropsten testnet. The chain is completely synced but my problem is that I can't post any transaction and also can't deploy any contracts. Pretty much everything that creates a transaction just isn't confirmed by the network. I am now waiting for more than ten minutes.
Any suggestions on what the problem might be? Is there a problem with the Ropsten testnet? The console output looks normal and I didn't have any problems to post transactions in the past.
