The web with Efold is that:
https://www.xiptic.com/es/download-es/
where if you click, for example over the text “Windows 7 – 64 bits – Actualización Sistema Operativo” nothing happens.

In this web that works with Theme “Ameya” (from Nayra Themes):

if you click “Windows 7 – 64 bits – Actualización Sistema Operativo” the “Page Template” opens in “http://www.biocap.es/?wpdmpro=windows-7-64-bits-actualizacion-sistema-operativo”
