Hi, first of all congrats, I love the theme.

I've had an issue , the instagram feed located in the home page just worked but since a few days the output is "Error type: Instagram has returned invalid data.Please double check that the username you are using exists. Or contact us if you are still having troubles."

The instagram account is https://www.instagram.com/casaruralshariqua/I attach you a capture of the settings of the block, I've docuble checked the settings and even tried to create a new instagram feed block with the same results. 
What can be causing this behaviour? Thanks in advance
