Error: cannot yet handle MBCS in html_entity_decode()! and others

[Nefeli]

I have installed SMF 1.1.3, TinyPortal v0.9.8, Coppermine 1.4.12 and copperminefetch-2.0.0

Recently I have changed host. Everything seems OK, categories, albums, cpmfetch etc, until i try to upload files .jpg

The error messages are

/include/functions.inc.php

    * Warning line 2933: cannot yet handle MBCS in html_entity_decode()!

/upload.php

    * Notice line 1972: Undefined variable: file_failure_array
    * Notice line 1973: Undefined variable: URI_failure_array
    * Notice line 1974: Undefined variable: zip_failure_array

Note that it tell me that the upload is successful.

If I press continue the upload corrupted and the message is

/upload.php

    * Notice line 2185: Undefined index: user1
    * Notice line 2186: Undefined index: user2
    * Notice line 2187: Undefined index: user3
    * Notice line 2188: Undefined index: user4
    * Warning line 2268: rename(): SAFE MODE Restriction in effect. The script whose uid is 10504 is not allowed to access /var/www/vhosts/nefelokokkygia.gr/httpdocs/Gallery/albums/userpics/10001 owned by uid 48
    * Notice line 2308: Undefined variable: PIC_NEED_APPROVAL

What can i do for that problem?
Sorry for my poor English

Turn notices_display off in Coppermine's config if they don't mean anything to you - they are a dev-only feature. Instead, do exactly as suggested in the upload troubleshooting section of the docs if you want help with upload issues.
