wordpress 3.9 and qtranslate issue
This morning I upgraded some wordpress blogs, where I am using the qtranslate plugin.
After upgrading to WordPress 3.9 the home page was broken.
Object of class WP_Post could not be converted to string in ../wp-content/plugins/qtranslate/qtranslate_core.php on line 455
To resolve this issue you need to edit a file:
In this file find function qtrans_strftime
and modify the line
return $before.($format, $date).$after;
return $before->post_content.strftime($format, $date).$after;
This will solve your issue.
