I have an existing plugin in Joomla where a 2CO purchase button takes a user to 2Checkout to pay after they have entered their name and email address. Upon successful purchase they must be subscribed to the acajoom newsletter(s) specified by the instance of the plugin. I use Joomla 1.0.x.
This plugin/Component used to work, but I have found today that it gives a "Parameter Error" instead of listing the product to purchase when the uysers click on the 2CO payment button, even for products for which it used to work.
You need to ensure that
1) The 2CO purchase works correctly
2) The users are successfully subscribed to the specified acajoom newsletters afterwards.
I suspect that this problem started after I asked my SP to have the setting cgi.fix_pathinfo=1 for php set on my server, but I am not sure.
I need a joomla and 2Checkout expert to resolve this problem for me urgently.
I'll supply the source code of the current plugin.
I can fix "Parameter Error" issue. User will be able to pay via 2CO. And will be subscribed "to the specified acajoom newsletters". I need FTP access to start right now.
