Your transaction is most likely in the mempool, whether that site (mempool.info) says so or otherwise (which it doesn't).
Your transaction size (5980 bytes) should have a fee of 0.0005 for priority. You placed a fee of 0.0001. That is too low.
There is currently around 4,300 txs in the mempool.
Since you have low priority, it may take awhile to see a confirmation (hours).
There may be "testing", "spamming" going on in the network, with conjugation of certain miners not filling their blocks on purpose.
Because of this, your transaction has been unconfirmed for hours.
Edit: BTW looks like mempool.info is broken and has txs claiming to be over 1 month old and older.
This is not possible because the mempool will automatically dump txs that are 48 hours old.
So that site must be broken.
