No Search Results - Uninitialized Values for $content

Hi everyone,

sorry to bother you with this but it seems that I'm stuck. For some reason I can't get beyond the "Your search did not produce any results" message. The index exists but does not seem to contain anything of value.

I am using version 3.31b, and I have to start the indexing through the browser as I don't have ssh access to the server. 

During indexing (done via http, not the file system) robots.txt and the first php file are fetched, but next appears the message

Use of uninitialized value at indexer_web.pl line 92.
Use of uninitialized value at tools.pl line 187.
Argument "

No more files are fetched, but the index is created anyway. What am I doing wrong here?

Thanks for any suggestions

Cheers, Michael
