The plugin is operating fine. My question is in relation to Google and their attitude to pages created using plugins such as MPG. There have been a number of google updates over the last few months, of which I’m concerned have prevented the indexing of pages created using your plugin. Most of the pages we have created have been discovered but not indexed by Google. I am confident this is not related to the sheer volume as I have created a sitemap with only 99 pages, of which 0 of them have been indexed by Google, despite being discovered.
Can I ask, is Google aware of how these pages are generated and are you seeing an increase in indexing issues with pages generated with your plugin?
I encourage you to test this for yourself. Please submit a sitemap consisting of pages created with your plugin and see if any get indexed by Google.
