Hi,
I can’t connect to your FTP, are there any IP or country restrictions in your server? and send me your backoffice access in a private also.
Best regards.
Fixed, the problem was caused by this code in the contact-form.tpl which was added by a module called slidecaptcha, I’ve removed it. {include file="$tpl_dir./../../modules/slidecaptcha/views/templates/front/slidecaptcha.tpl"}
