Hello, I'm experiencing a problem when I activate the polylang plugin.
The content isn't display anymore and when I print out the debug info, I can read the following error :
"Fatal error: Call to undefined function mb_convert_case() in /data/myapp/www/wp-content/plugins/breadcrumb-navxt/breadcrumb_navxt_admin.php on line 847"
Does anyone can help me ?
I'm using :
*wordpress version : 3.1.3
*polylang version : 0.8.6
Thanks,
Best regards,
Ben
