Hi Kazimierz,
It looks like the ftp provided does not belong to the site discussions.ecomolfa.com. Can you help me check the following file,
JoomlaFolder/components/com_easydiscuss/themes/wireframe/mypost/default.item.php and make sure the following line in the screenshot is like this(
http://take.ms/tD4BD)?
If not, can you provide me the ftp access to that site so I can investigate?
