Problem with my Server

Sorry I do not speak english. I write with a translator.
I have problem with my Plesk 12.30, Debian 7.9, Linux, FastCGI. VServer is freshly installed.

01- pictures I will upload not displayed. but which are present in the folder upload. it's a subdomein.

02- I have a script Avatar me the man can write on images texts online. The ü öä are not displayed properly.

03- My emails are not sent. All mails that I want to send are in the queue of Plesk. But I get mails without problems.

Please...
