Update lief schief - u.a. Adminbereich nicht mehr erreichbar

[Kommunarde]

Nun hab ich da wohl vermutlich etwas verbockt. Bei mir lief das Update 3.0 -> 3.1 wohl etwas schief und ich würde Hilfe benötigen.

1.) Zunächst mal erscheint beim Öffnen des Forums ganz oben folgendes:

[phpBB Debug] PHP Notice: in file /includes/functions.php on line 3289: Undefined index: HIDDEN_USERS_ZERO_TOTAL_AND
[phpBB Debug] PHP Notice: in file /includes/functions.php on line 3526: Cannot modify header information - headers already sent by (output started at /includes/functions.php:2948)
[phpBB Debug] PHP Notice: in file /includes/functions.php on line 3528: Cannot modify header information - headers already sent by (output started at /includes/functions.php:2948)

[phpBB Debug] PHP Notice: in file /includes/functions.php on line 3530: Cannot modify header information - headers already sent by (output started at /includes/functions.php:2948)

2.) Melde ich mich für den Adminbereich an erscheint nur:

[phpBB Debug] PHP Notice: in file /includes/functions.php on line 210: Undefined index: MIB
[phpBB Debug] PHP Notice: in file /includes/functions.php on line 215: Undefined index: KIB

Was muss ich tun um meinen Fehler zu bereinigen ???

[Kommunarde]

Problem gelöst.

Lösung: das deutsche Sprachpaket war meinerseits falsch installiert.

Fazit: es bestätigt sich wieder, dass der Fehler meistens vor dem Monitor sitzt.

Sind deine Sprachdateien aktuell ?

//edit: Das hast du dein Problem schneller gelöst als ich posten konnte.
