Please try this suggestions:
1) Deactivate any plugin that you have installed, specially the third-party ones (if any).
2) Activate the debug mode and share a screenshot of this page: www.beanscorner.org/blogs/blog2.php. (how to: http://b2evolution.net/man/advanced-customization/debugging/debugging)
3) Clear your site's cache at System > Maintenance > Tools
