Me uno al tema.

A mí me pasa algo parecido en uno de mis proyectos con Prestashop 1.7.2 

Si pongo modo debug me da un error de Smarty de caché muy parecido también y si pongo modo normal me funciona todo correctamente .

Estoy casi seguro que si se limpia el directorio de caché el problema se solucionaría, pero como no estoy seguro no lo hago.
