I have been using phpList on my server (managing about 200,000 records) for 5-6 years and am a huge fan. I recently migrated from version 2.x to 3.2.4, and lost the ability to apply attributes to extract subscriber subsets from lists in the campaign manager. I am a legacy user upgrading from within the application, so I wasn’t even aware of the new phpList.org website or the plugin architecture.
Google top search results for troubleshooting this problem point to docs.phplist.com, which has a heading, II Userguide -> Configuration Functions -> Attributes, describing an Attributes tab which is non-existant in the current default version. A subsequent Google search on “missing phpList Atttibutes tab” yields a lot of confused user questions, but not a lot of competent solutions. Following suggestions for editing config.php and modifying code led to a single post saying “I think there’s a plugin for that,” prompting me to do a manual drill-down to find and install the (excellent) Segment plugin (and the required base plugin).
I was going to post this to the forum to help others going through the same experience and discovered the new website (with the more complete documentation). I don’t know if docs.phplist.com is maintained or deprecated, but perhaps a link on that landing page pointing to the newer manual would be really helpful for those of us that land there by virtue of Google or old bookmarks?
