Please do not post extensions/template specific questions in the "Free stuff" forum. You should post in the extension forum or template forum as appropriate. Most of these forums are for members who have a current PAID membership. Our priority is always to assist paying members.
Thank you for your understanding.
You subscription expired many years ago. Support does require a current subscription.
Please ensure that everything on your site is up-to-date - Google changed the recaptcha API a while back and that forced joomla to fix this in a later version of joomla.
You also didn't post a link so there nothing for me to check in any case? - look in browser console too for error messages.
Regards, Mark.
