the vertical list mode works fine.....
index.php?option=com_jux_eventon&view=events&list_style=grid&Itemid=1574&venue_id=11&c_id=0&button=Αναζήτηση&limitstart=10
the horizontal mode should have this link not index.php?option=com_jux_eventon&view=events&Itemid=1574&limitstart=10
i opened mod_jux_eventon_eventsearch / tmpl / horizontal.php deleted everything after line 39 went to mod_jux_eventon_eventsearch / tmpl / vertical.php
and copied everything below line 39 and pasted in the horizontal.php and this fixed it.the code is wrong on horizontal template...implement this fix in the next release so that i can purchase an update in the future without issues.
