Backup records (table) to Excel

When I try to make a backup of the table to Excel, I get the following in my sheet:

<br />
<b>Warning</b>: tempnam() [<a href='function.tempnam'>function.tempnam</a>]: open_basedir restriction in effect. File() is not within the allowed path(s): (/home/alpenroos/:/tmp:/var/tmp:/usr/local/lib/php/) in <b>/home/alpenroos/domains/alpenroos.be/public_html/administrator/components/com_chronocontact/excelwriter/PPS/File.php</b> on line <b>87</b><br />

Sorry, but I don't understand what this means...
What should I do?

Hi Rogier,

Your ISP has the open_basedir security system enabled and the current settings don't allow the Joomla! user to write the temporary file needed to create the export.

I think that the temp folder is the one declared in your Joomla! settings - usually [root]/tmp. See Global Configuration | Server |Server Settings for the current path.

You probably need to talk to your ISP or check their help files to find out what has to be done.

Maybe this could be of any interest:
The problem occurred since I moved all the folders and files from the joomla-folder up 1 level to the public_html-folder. Before that the backup to an Excel-file worked well with the test-records I made.
