Ok, it seems my message is unclear. Let’s try again.
Your theme contains links to sites: schema.org and placehold.it
Both sites are HTTPS, not HTTP. And the theme links to HTTP versions. As an example /lib/custom.php line 149:
$schema = ‘http://schema.org/’;
And if in a case of schema.org it`s just a good practice to replace HTTP with HTTPS, in case of placehold.it it breaks security because of unsafe image load, which is bad.
Hope I explained better now.
Submited. Thanks for help.
Sry, forgot to add “Erick”.
Im not sure about your problem guys, but for me problem was with tweet length. It was worked with <140 and did nothing with >140. I think you guys should try to activate bit.ly posting and it might work for you. Just check if your tweet more than 140 symbols.
