Itp share joomla 2.5 - The image dont appear 

Dear Friends,

We use your plugin FTP SHARE on our customer www.midas.med.br and it was so good. 

But, now, this plugin is making a mistake

When we play to share on facebook or others web social, dont appear the article image. Only appears the MIDAS's imprint image.

We try to save an new .htaccess,  but dont works. 

We try to disable the gzip funcion into the joomla's global configuration, but dont works,

We dont know what more can be do to solve this problem

May you help us?
