I download the zip package but after copying via FTP, i flushed the cache and update the index management.
After i log in again in my admin. When i try to access the Slideshow/Settings (/Posts; /Posts Revolution) it return a:
"my domain" is currently unable to handle this request. HTTP ERROR 500.
Also i cannot find the settings tab in admin Configuration/Settings (because i already use an extension from you "CMSMART MEGAMENU") no New or Settings tab for this module.

Thanks.
