Hi Beetlefish,

Thank you for your interest in my plugin.
Unfortunately you have installed an old plugin which has not been updated for years (and which is not mine). Please uninstall the current plugin and search for Nextgen Gallery Search version 2.0 by By the W WW…

If you have any questions please let me know.
