It kinda works if I deactivate my paypal plugin, but I sometimes get this message:
Warning: Cannot modify header information - headers already sent by (output started at /home/metiersd/public_html/wp-content/plugins/polylangfix/polylangfix.php:1) in /home/metiersd/public_html/wp-includes/pluggable.php on line 876
Since I'm quite happy with my simple paypal shopping cart plugin, I don't know what to do. :-(
(polylangfix is the name I gave the new php file and the folder I put it into)
