thanks if solved :)

anyone there !

About the issue with chatblock: the paths are strange, check its settings. Your webspace's root it's actually /membri/ieee/.
The other problem is likely caused by the .htaccess file in the root directory, delete it.

about chatblock, its confusing, correct me.

I don't understand, what do you mean?

ok, leave chatblock, which one if i delete the default alter htacces , isn't it danger, security reasons.. Thanks

I dont know why u guys dont give reply,

The 500 error is caused by the .htaccess on your webspace's root. Delete that file.

done, and also redirected 500 to page index.
