Me da un error con plugin

[remacomputing]

Hola, tengo el plugin mygeopositioncom y al activarlo me da una serie de errores. Tengo 2 blogs y me sale tanto en uno como en otro.

En las paginas me da este error:
Warning: Illegal string offset ‘addMap’ in /homepages/42/d489729608/htdocs/wp-content/plugins/mygeopositioncom-geotags-geometatags/mygeopositioncom-geotags-geometatags.php on line 605

y en el admin me sale este error:
Warning: Cannot modify header information – headers already sent by (output started at /homepages/42/d489729608/htdocs/wp-content/themes/eleganttwo_21/WordPress_Version/functions.php:208) in /homepages/42/d489729608/htdocs/wp-includes/option.php on line 571
