[CWB] Help: CQPweb Corpus Installation and Deletion Error

[yuyuan97 at 163.com]

Dear All,
A few days ago, I decided to have a go with the CQPweb on a Ubuntu machine,  and there was no problem of installing the CWB and other prerequisite packages at all.
 I also managed to re-encode the sample Dickens corpus  in order to experimenting its installation on the CQPweb.  Now the problem is that I ended up with a failure at the last step when I was trying "installing with a pre-indexed corpus",  to create the metadata for the corpus, and I am prompted "The requested URL /dickens/index.php was not found on this server. "
I contacted Andrew, he thought it might be permission problem to the CQPweb directory.  I  changed owner of the CQPweb directory in the /var/www directory to www-data with the same user name as  the CQPweb admin, I did so with the four additional directories created for CQPweb too.
 Now when I am deleting the unsuccessfully installed two corpora (I tried twice) from the CQPweb admin contrl panel, it ended up with the error message:
    """
    Fatal error: Call to undefined function delete_xml_metata_for() in /var/www/CQPweb/lib/admin-lib.inc.php on line 265
    """
 I would be grateful if anyone can help or offer me some suggestions.
 
Best regards and many thanks in advance,

Yu Yuan
