we have a little issue on a jevelin website that is in 2 languages. After submitting the message on a unyson front page’s contact form, the bar appears just on one, also with the wrong language. On the other language it doesn’t appear at all.
thank you for the quick answer and for the hint. We deactivated WP Super Cache plugin and now everything works right.
Do we need to eliminate and never use again the plug-in? Would it be that bad for the website performances? If so can you suggest us any alternative please?
