Error message editing photo!

Hi,

When editing a photo I get this message:

Warning: implode() [function.implode]: Invalid arguments passed in /home2/myiappea/public_html/inc/classes/BxDolFilesModule.php on line 460

Warning: Cannot modify header information - headers already sent by (output started at /home2/myiappea/public_html/inc/classes/BxDolFilesModule.php:460) in /home2/myiappea/public_html/inc/design.inc.php on line 133

The file does get saved and the changes are made.  Can anyone tell me how to fix this?

Thanks

I should note that I removed the Categories field!

I made the following change in:  /inc/classes/BxDolFilesModule.php

About Line 460

/* else {

$aValues[$sKey] = implode(CATEGORIES_DIVIDER, $_POST[$sKey]);

} */

The problem seems to be fixed!!
