Cronjob for spidering doen't work anymore with PhpDig 1.8.6

[gaam]

Hello,

Our ISP has troubles to do a cronjob for spidering the site since I updated PhpDig to 1.8.6. Before in 1.8.0 the cronjob calls an URL to start the spider.php.
But now I can't call the spider.php because I have to login first.

Our ISP tried to setup a cronjob per command line, but then he run into this error:
-------------------------------------------------------------------
Fatal error: Call to undefined function: phpdigprnmsg() in
/www/marbach/phpdig/admin/spider.php on line 128
--------------------------------------------------------------------------

What is going wrong here?

And then there is another problem: When I log in and call spider.php then PhpDig doesn't spider:

Der Spider arbeitet gerade... [Spider anhalten]
Optimizing tables...
Indizierung abgeschlossen!
[Zurück] zum Admin-Interface.

When I use the Admin-Interface and then Update Form (URL) then it works fine.

Thank you for helping.

Regards,
Markus
