PO payment module installation problem

[basnyd]

Hi -

I have a weird problem and so far I have not been able to figure it out. I hope someone here can help.

If I go under Payment modules on the admin piece everything looks good. Credit Card and COD are the only modules activated. I can see the column to the far right that allows me to install/edit/remove each module.

However, when I upload the po.php in the catalog/includes/modules/payment directory and I go back to Payment under the admin piece to activate the module, I don't see the module listed. I don't the the option to select "Purchase Order" under the payment section and the right column that use to allow me to "install/edit/remove" each module is gone (I can't see it).

If I removed the PO.php file from the module directory everything goes back to the way it should. I've looked at the po.php file, but I can't see anything that is causing the problem. I removed the blank line at the end of the file, but that didn't help.

Any suggestions are greatly appreciated. This was working at one point, unfortunately I can't figure out what changed and why I can't install it now. This is the module I'm installing osCommerce Community Add-Ons

Thank you,
Barb

I put back the original files I downloaded. I no longer have this problem.

for what it's worth, I just modified COD and tell them to put their PO number in the comments field.
