title/description/tags are missing / grey

The grey entries are placeholders, these display what the plugin is dynamically generating for you. The plugin has always done this, we just didn’t display it in those fields as placeholder text but as this was something that many users asked for we added placeholder text.

Perhaps I was not precise enough, the problem is that there is no metadata attached to each page/post ! Namely, in the post/page view SEO title/description/keywords are all empty. Google webmaster shows metadata errors for all pages/post, which is far from good.

Can you provide a screenshot and a URL please.

here is a link to a screenshot: https://www.dropbox.com/s/020a4en4vcvp61n/no-metadata.png?dl=0

and the website is https://portraits-of-unknown.com

The plugin is working correctly. I checked one of your posts and the plugin is generating the Title tag and meta description correctly. I see no problems.

https://portraits-of-unknown.com/young-russian-photography-part-i/
<title>Young Russian photography. Part IPortraits of Unknown | Portraits of Unknown</title>
<meta name=”description” itemprop=”description” content=”Elina Ryzhenkova is the young artist from Russia. She studied psychology, then she became interested in photography and later in contemporary painting. She is” />

sorry, my fault.

What is actually missing according to google is author, entry-title, updated data. Here is a screenshot: https://www.dropbox.com/s/c49sop9pm4tdypl/missing-entries.png?dl=0

Can one control these fields in All-in-one SEO?

This is alerting you to the fact that your theme does not include that HTML markup. It’s fine that the theme does not include that markup, many themes do not. However, this is a theme issue and something that can only be fixed in your theme.

thanks a lot for detailed explanations!
