Hi grosbouff,
am I right that "Pinterest" apparently changed the code of their login page again ? So "Pinterest Importer" can't find the "app version" anymore ? I did a quick&dirty adaption of your code in 'pinim-class-bridge.php'. I replaced
preg_match('/P.main.start(({.+}));/isU', $body, $match);
with
preg_match('/P.startArgs.=.({.+});/isU', $body, $match);.
This worked for me. Maybe you could have a look at your code and update to 0.2.7.
Thanks a lot
Marc
