authorize.net (AIM) forms disappearing from the screen

[needslotsofhelp]

Here is the problem. Every time I click on anything inside the payment module, the authorize.net aim disappears off the screen. Even if it is on "true" it still doesn't show up. the only way to make it appear is the hack the database and add authorizenet_aim.php to the INSTALL_PAYMENT_MODULE in the configuration table (line 142). Otherwhise it will not appear.

Anyone else have this problem?

sounds like you have some corrupt files uploaded to your server, or else you have some modules installed that aren't playing friendly.

I'd try:
- removing all modules that didn't come with Zen Cart
- re-upload original files after re-unzipping them. Use a reliable FTP program like FileZilla (and not SmartFTP or cuteFTP)

If all else fails, it may be necessary to do some harsh diagnosis:
