Elgg 1.8.15 with Twitter still not connect (i use free virtual host)

haloo all.

I'm elgg newbie.

When i install my elgg on 000freespace i found that elgg must be install at subdirectory for 'data' folder reason.

For other services and plugins its ok, but twitter_api don't work, so soialconnect, sociallogins plugins they dont work either....

Any Idea ? please help me.... this my site : http://ulilalbaab.000space/ua
