How do I change blog title?

Perhaps you could try clearing your browser’s cache?

tried, but same problem.

Have you changed the template files? Could it be possible that the title was typed into the template instead of being pulled from the settings page?

Do you have the tagline displayed and if so does that update successfully?

what template files? how do i edit?

i’ve solved the problem. it is overwritten by the “all in one seo” plugin.
anyway, thanks for your help.
