Division by zero in <- Problem. Need a solution!

[Raidu]

Hello,

I'm working on a e-shop for my client, but the VirtueMart is giving me a hard time. I am running on 1.7 joomla and the problem is:

COM_VIRTUEMART_MEDIA_NO_PATH_TYPE <- I have set the paths to media via config, but it still is giving me this error.

Warning: Division by zero in components/com_virtuemart/views/categories/tmpl/default.php on line 32 <- I have no idea how to fix this one

and this one:

Warning: Division by zero in components/com_virtuemart/views/categories/tmpl/default.php on line 54

The code lines are under here:

Line 30. // Calculating Categories Per Row
31. $categories_per_row = VmConfig::get ( 'categories_per_row', 3 );
32. $category_cellwidth = ' width'.floor ( 100 / $categories_per_row );

Line 53. // Show the vertical seperator
54.   if ($iCategory == $categories_per_row or $iCategory % $categories_per_row == 0) {
55.      $show_vertical_separator = ' ';
56.   } else {
57.      $show_vertical_separator = $verticalseparator;
58.   }

Please help me out! I need a fix asap.

what do you have for "Default number of categories in a row" in your config?

I think that his config values are cleared!
You can get it up by log in to VM admin -> Menu Tools > Update > Restore System Defaults

Pls check your http://joomquery.com/administrator/components/com_virtuemart/install/virtuemart_defaults.cfg
And Make it writeable (CHMOD 755 or 777)

This is very interesting. The file shouldnt needed to be writeable, only readable. Further tests would be nice.

Sory for my Bad english but I have sugession:
Line 30:

Code Select Expand

// Calculating Categories Per Row
$categories_per_row = VmConfig::get ( 'categories_per_row', 3 );
Replace to:

Code Select Expand

// Calculating Categories Per Row
$categories_per_row = trim(VmConfig::get ( 'categories_per_row', 3 ));
if (($categories_per_row!=""))&&(!is_int($categories_per_row)){
$categories_per_row ==3;
}
** EDIT: please respect the forum and community and do not advertise in posts **

the bug is that VmConfig should do that already internally.

This doesn't work for me. I've tried a variety of categories-per-row values, but that doesn't help either.

Please try the version in svn. Use "renew config by file" and it should work then.
