Parse error means that there is something wrong in your API request format.
answered Mar 20, 2019 by gimmick
Can you please let me know when this error shows up to you?

Generally this error pops up when you make some API request to the blockchain and the format in which you are making request is not correct as it should be. As, there are some predefined parameters and predefined way to make request in multichain so if you have not made up your request in that format then you will face such an error.

If you uncomment the two lines in file functions.php in the Web Demo files that contain:

echo '<PRE>';

Then you will see more about the request sent and response received. You can post them here as well and we should be able to help more.
