Google says: Wrong File Format

[Kelley1995]

Hello,

in the Google webmaster's tool a note appears, which explains that the data from the XML site cannot be read due to a wrong file format...

I am currently using 1.2.11 on my main page and that is where the error occurs. With 1.2.7 (as in other implementations) everything works well.

Would you please advise me, what I can do?

Would you please send me the 1.2.7 version again?

Thank you for your help,
best regards
Kelley
