How to fix Nikon Error Press Shutter Release Button Again DSLR

If you own a DSLR and suddenly an error of &Shutter Release Again&pops up and it wont take any pictures although you press the Shutter repeateDly,what would you do? I had this problem a week ago on a vacation using my 1st beginner&DSLR ,a Nikon D3100. This can easily happen if you drop your cam too If its under Nikon Warranty,you can turn in to the dealer & wait for the repair but what if its beyond warranty period, or you bought it used with expired Warranty? Here&my solution to fix it to save some repair charges and guess it might bless someone with the same problem there. Theres a small hinge thats blocking the shutter to release ,press it through and it should be fine :)
