Hi, I followed Jan Dembowski's instructions, and it looks great on Firefox, except I get this message under my WordPress bar:
Warning: join() [function.join]: Invalid arguments passed in /home/content/44/10371344/html/wp-includes/post-template.php on line 389
I checked in Chrome and there is no change - i,e, no sidebar.
I tried alchymyth's option, but that gave me this error message:
Warning: Cannot modify header information - headers already sent by (output started at /home/content/44/10371344/html/wp-content/themes/twentyeleven-bigbirthas/functions.php:17) in /home/content/44/10371344/html/wp-includes/pluggable.php on line 876
And didn't make the sidebar appear anyway.
I don't want to use the Moztools plugin because it's not been tested with the latest version of WordPress and it also messes up my bbpress forum page (which I took ages getting right)
Any ideas gratefully received.
The website is bigbirthas.co.uk if that helps anyone.
