GUI does not have necessary privileges

Hello.

I just installed Asterisk, and i’m trying to access configuration panel.

I’m trying to get here:
localhost:8088/asterisk/static/c … basic.html

but it redirects me here:
localhost:8088/asterisk/static/config/index.html

So I tried loging in using user and password specified in manager.conf, but it gives the following error:

The GUI does not have necessary privileges.
Please check the manager permissions for the user !

Here is my manager.conf:

;
; AMI - The Asterisk Manager Interface
; 
; Third party application call management support and PBX event supervision
;
; This configuration file is read every time someone logs in
;
; Use the "manager list commands" at the CLI to list available manager commands
; and their authorization levels.
;
; "manager show command <command>" will show a help text.
;
; ---------------------------- SECURITY NOTE -------------------------------
; Note that you should not enable the AMI on a public IP address. If needed,
; block this TCP port with iptables (or another FW software) and reach it
; with IPsec, SSH, or SSL vpn tunnel.  You can also make the manager 
; interface available over http if Asterisk's http server is enabled in
; http.conf and if both "enabled" and "webenabled" are set to yes in
; this file.  Both default to no.  httptimeout provides the maximum 
; timeout in seconds before a web based session is discarded.  The 
; default is 60 seconds.
;
[general]
displaysystemname = yes
enabled = yes
webenabled = yes
port = 5038

;httptimeout = 60
; a) httptimeout sets the Max-Age of the http cookie
; b) httptimeout is the amount of time the webserver waits 
;    on a action=waitevent request (actually its httptimeout-10)
; c) httptimeout is also the amount of time the webserver keeps 
;    a http session alive after completing a successful action

bindaddr = 0.0.0.0
;displayconnects = yes
;
; Add a Unix epoch timestamp to events (not action responses)
;
;timestampevents = yes

[mark]
secret = mysecret
;deny=0.0.0.0/0.0.0.0
;permit=209.16.236.73/255.255.255.0
permit=127.0.0.1/255.255.255.0
;
; If the device connected via this user accepts input slowly,
; the timeout for writes to it can be increased to keep it
; from being disconnected (value is in milliseconds)
;
writetimeout = 100
;
; Authorization for various classes 
;read = system,call,log,verbose,command,agent,user,config
;write = system,call,log,verbose,command,agent,user,config
read = all
write = all

and here is my http.conf:

;
; Asterisk Builtin mini-HTTP server
;
;
[general]
;
; Whether HTTP interface is enabled or not.  Default is no.
;
enabled=yes
;
; Whether Asterisk should serve static content from http-static
; Default is no.
;
enablestatic=yes
;
; Address to bind to.  Default is 0.0.0.0
;
bindaddr=127.0.0.1
;
; Port to bind to (default is 8088)
;
bindport=8088
;
; Prefix allows you to specify a prefix for all requests
; to the server.  The default is "asterisk" so that all
; requests must begin with /asterisk
;
prefix=asterisk

; The post_mappings section maps URLs to real paths on the filesystem.  If a
; POST is done from within an authenticated manager session to one of the
; configured POST mappings, then any files in the POST will be placed in the
; configured directory.
;
;[post_mappings]
;
; In this example, if the prefix option is set to "asterisk", then using the
; POST URL: /asterisk/uploads will put files in /var/lib/asterisk/uploads/.
;uploads = /var/lib/asterisk/uploads/
;

Any one got any clues?
