[SOLVED] - Attributes page is blank - New installation

Hi all

I have just now installed a new Opencart, latest version. Everything seem to work smooth exept the Attributes page in the admin pane. It just goes blank. Attribute groups work fine.

Does anyone have an ide to what i should check out to make it work ?

Searched the forum, and amogst a few pointers I have checked the mbstring() function, it is on:

mbstring
Multibyte Support enabled
Multibyte string engine libmbfl
HTTP input encoding translation disabled

mbstring extension makes use of "streamable kanji code filter and converter", which is distributed under the GNU Lesser General Public License version 2.1.

Multibyte (japanese) regex support enabled
Multibyte regex (oniguruma) backtrack check On
Multibyte regex (oniguruma) version 4.7.1

Directive Local Value Master Value
mbstring.detect_order no value no value
mbstring.encoding_translation Off Off
mbstring.func_overload 0 0
mbstring.http_input pass pass
mbstring.http_output pass pass
mbstring.http_output_conv_mimetypes ^(text/|application/xhtml\+xml) ^(text/|application/xhtml\+xml)
mbstring.internal_encoding no value no value
mbstring.language neutral neutral
mbstring.strict_detection Off Off
mbstring.substitute_character no value no value


EDIT: I noticed a few of the files on the server was 0kb. I uploaded the files again, and problem was fixed.
Anyone got some other steps I should check ?
