WordPress version: 3.4.2
WordPress SEO version: 188.8.131.52
I did this: I installed SEO Yoast. Changed my permalinks. Redirected via htaccess. All (old) search results work. No problems with that.
I expected the plugin to do this: I have custom code for the add-this sharing buttons placed in the plugin custom box. No problems for a year. Installed SEO and those buttons are not properly showing up on posts. On the home page they are showing up correctly.
Instead it did this: I noticed that if I go into a post and manually edit the description meta, and add a keyword, "sometimes" the buttons will show up on the individual page.
Read an old post which recommended I check the calls (the_content) rather than get_the_content(). which I am already using.
