I just installed the PRO version of JoomSEF (4.5.2). I'm getting the same error as a previous user, but could not find a resolution.

Warning: Illegal string offset 'class' in /home/web/mysite.com/ftp/www/libraries/cms/html/html.php on line 965

I understand that it is not coming from the JoomSEF component, but could you please assist, as this error is occuring from within the JoomSEF component and nowhere else? Thanks for any support you can provide.
