Finished upgrade to 2.6 and had to fix a weird issue with disappearing categories. Hopefully, the pages will be indexed now. If anyone else has had a similar problem (with the pages not being indexed), which got fixed (meaning, pages were indexed again) when you upgraded your wordpress version, please let me know.
Some people suggest that the reason why WordPress blogs are not being indexed is because owners failed to update the WordPress version. See:

That’s why I was asking about the version issue.
