Bug report: Throws error for https logged-in user posting on http page

On wpDiscuz default settings, Posting comment on http as https-logged-in author worked a couple of days ago, but today suddenly began throwing errors unknowingly.

Throws error “Invalid Captcha Code” when CAPCHA is shown
Throws error “Some of field value is invalid” when CAPCHA is hidden.

In the end from an hour of tracing, they are all phantom errors because the real cause was the mismatch between logged-in protocol and posting protocol. Took me about an hour to find out why i couldn’t post as logged-in author today when i just did a few days ago.

Please fix this error, especially for people who use the following in wp-config.php to enable https for the login & the admin panel only and not for viewing the site (the default behavior this feature):
define('FORCE_SSL_ADMIN', true);

Has been a great plugin. Glad to have found a workaround tho. hope the fix comes soon, till then i have to type https:// in order to post as author.

p.s. In my debugging, i tried the following:
– remove all plugins except wp-discuz
– decided to create a new wordpress installation with the https option enabled and i reproduced the bug.
