Problems with multisite

    I converted an existing large site with over 1000 user subscriptions to multisite. Afterward, users noted that their subscription preferences had all gone blank. I was able to solve the problem by changing the wpmu check on line 1620 of class-s2-core.php:

    I replaced this:

    // Is this WordPressMU or not?
		if ( isset($wpmu_version) || strpos($wp_version, 'wordpress-mu') ) {
			$this->s2_mu = true;
		}
		if ( function_exists('is_multisite') && is_multisite() ) {
			$this->s2_mu = true;
		}

    with this:

    if (is_main_site()) {
			$this->s2_mu = false;
		}else{
			$this->s2_mu = true;
		}

    Can you suggest a better long term solution or add this check to the plugin so subscriptions don’t break on plugin upgrade? Thanks!

  • @gtrout,

    This issue has probably only arisen because you converted a single site WordPress install to a multisite one.

    Also, the is_main_site() function returns true or a number which is the blog id of the current site, so your fix probably won’t work reliably without further checks.

    A longer term fix would be to import all of the users from the old blog to a sub-blog on your multisite.

    Thanks for your quick reply!

    I’m not sure I understand your advice. The “old blog” is still the main site. There are several sub-sites, each of which has a small subset of the main user base.

    The problem seems to be that the original subscriptions are stored in wp_usermeta with the key s2_subscribed but that with multisite enabled you’re looking for a key with the wp_ prefix like wp_s2_subscribed.

    @gtrout,

    A fix may well be to user PHPMyAdmin or similar to rename all of the existing keys in the wp_usermeta table called s2_subscribed to wp_s2_subscribed. In multisite Subscribe2 needs to keep the settings for each blog separated. It does this by prefixing the database prefix for each subblog to the meta key name.
