parsererror

[micbal]

Hallo an ALLE.
Bin leider nicht so versiert wie viele von Euch hier.Deshalb bin ich bei meinem Problem für jede Hilfe dankbar:

Es geht darum das eine Installation gemacht werden soll.Leider erscheind immer wieder die gleiche Fehlermeldung:

AJAX error:

parsererror(undefined)Raw Data:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<restoredata>
<error><![CDATA[No database definitions were found or no database was selected.
]]></error>
</restoredata>

Nun was ich sicher weiss ist das folgende Einstellungen von mir Richtig vorgenommen wurden:

server host (dbXXXX.1und1.de),username (dbo34077XXXX), password (XXXXXXX),database name (db34077XXXX)
sieht aus weil die leere Datenbank bei 1&1 angelegt ist und mit MySQL5.0läuft .

Wäre echt klssse wenn ihr Spezialisten hier helfen köntet.

Kannst du dein Problem vielleicht näher eingrenzen. Ich vermute z.B. dass ein AJAX-Error nichts im PHP-Forum zu suchen hat.

Wer/Was meldet diesen Fehlern? Im Quellcode taucht das Wort AJAX nämlich nicht auf!

[ThemBones]

Hallo,

welche Software versuchst du zu installieren? Was allgemein bekanntes?

Ich würd jetzt einfach mal laut dieser Fehlermeldung drauf tippen dass ganz einfach bei der Konfiguration was nicht stimmt (falscher DB-Name o.ä.).

Ausserdem, du solltest deinen Code umbrechen, dann wird das auch gern gelesen. So muss man scrollen
