'website' is invalid; required property 'og:title' of type 'string' no

after updating my wordpress to 4.2.4 and then updating my yoast SEO, i suddenly have some problems sharing my articles to Facebook. No title, picture and excerpt appear when shared on FB. And when i use the FB Open Graph Debugger, the error below appears.

Object at URL ‘https://www.pinoyswimming.com/2015/08/06/motivational-times-female-ranking-lc-season-leaders/’ of type ‘website’ is invalid because a required property ‘og:title’ of type ‘string’ was not provided.
Warning
Curl Error : OPERATION_TIMEOUTED Operation timed out after 10000 milliseconds with 0 bytes received

is this problem caused by Yoast? or what? please help!
