Hi,
We have just got round to using this and added a facebook and a twitter link#
Both of them are NOT showing thumbnails and in the error log we have errors like this
01/05/2017 04:07 PMlinksIPS\Http\Request\CurlException (28) Operation timed out after 10001 milliseconds with 0 bytes received
When opening up the errors we have the following info in backtrace field
