Multisite issue

Hi,
Polylang support advised me to reach out to you regarding this issue. I just wanted to duplicate the information about the problem here for your reference
https://ww.wp.xz.cn/support/topic/multisite-issue-64/#post-18632201

The issue appeared in version 3.7, and translation strings are no longer displaying correctly.

After investigating, here’s what I found:
$settings = Polylang_Theme_Translation_Settings::getInstance() returns the wrong settings, because it always pulls from blog_id = 1, while I’m actually on blog_id = 2.

The problem seems to come from the global $wpdb variable. It doesn’t switch to the correct blog, so $wpdb->options always points to wp_options instead of wp_2_options when trying to fetch the settings.

I suspect switch_to_blog() (and restore_current_blog()) might be involved and not being used correctly anymore.

Could you please check your commits to see where this behavior might have been introduced in 3.7?
