Wordpress not reading the wp_postmeta.meta_value

I have a problem with word press not displaying the SEO title from All in One SEO plugin. I have looked at the wp_title() which then goes to the single_post_title() but can not see anything that is looking up the wp_postmeta.meta_value开发者_C百科 in the database only post_title.

Maybe this is a part of the plugin but where does the plugin overwrite the default behaviour of word press <title>.

Check your Theme:

• is wp_title() and wp_head() called, as I suppose All in one SEO-Pack is hooking into one of these functions
• does it use an own mechanism to generate a title?
• is a title generated in your Theme and the title from the All in one SEO-Pack is generated below, so it is not recognized?

If there is everything ok with your Theme, also the All in one SEO-Pack will work, i suppose. If not, deactivate all other Plugins to check if one of these is overwriting or hooking into the title functions, so that the All in one SEO-Pack can not take action.

Hope this helps.
