I dont see the point in having that many SEO pkugins. All of them do pretty much the same thing. The one i like the best is All In One SEO Pack. The reason you are getting the error is because some of those plugins are trying to do the same thing
Just choose between Platinum SEO Pack or All in One SEO plugin. That will be enough. You won't get traffic just by installing SEO plugins though. You need to do other things as well. Installing incompatible plugins can cause errors on your blog.
You should use only "All In One SEO Plugin". It is the best plugin and sufficient for increasing traffic. As you have installed so many plugins in your blog therefore "You Got An Erro About Database Erro". These plugins use more CPU and more load on server due to this database error generate.
Adding a bunch of plugins isn't going to get you traffic, it's what you do with those plugins is what matters. I use "All in 1 SEO plugin" and "Google Sitemap". You really need to write original content and not just source other sites (SE's don't like that). Also you need to research keywords for each post title and post url along with the home title, home description, and home keywords. Use the Google Keyword Tool https://adwords.google.com/select/KeywordToolExternal to find keywords that get searched and don't just sound good. I would also think about increasing your posts per page to 5-10 (instead of 1) and adding a sidebar and more content to each page. Also the standard wordpress theme is pretty boring so you may want to change that.
Apart from installing plugins, you also need to do offpage optimization to get natural traffic from SE.
my fav seo plugin is: AIO SEO or Platinum SEO STT2 SEO booster Pro SEO Smart Link too many plugin can cause error and spend your hosting resources
