Hello again,
I was checking yoast.com a few minutes ago and noticed in the source that you have this line: <!-- This site is optimized with the Yoast WordPress SEO plugin v0.3.5 - http://yoast.com/wordpress/seo/ -->
I was then checking the source of this page: mediasinfo.ro where that line is missing.
Both sites are using the latest version of WordPress SEO. Both are using W3TC, but on the latter the version of W3TC is 0.9.1.3 due to increased number of bugs in the latest version of the plugin.
So questions are:
1. is wordpress seo working on my site?
2. why don't I see the lines?
3. what settings are changed in the W3TC that might influence the behavior?
Many thanks!
