To successfully install Ioncube on 1and1 hosted sites, follow this procedure:

1) Upload the 'ioncube' folder from the PAPs distribution zip package into the root of your hosting webspace.

2) Create a new php.ini file using notepad or any other text editor.  Inside of this file put the following code:

zend_extension=/homepages/xx/dxxxxxxxxx/htdocs/xxx/ioncube/LOADER_FILENAME

(Put the relevant parts for your specific server path where I have put the x's.  You can find this path out from your 1and1 control panel. You can ascertain the required LOADER_FILENAME by reading the 'General Installation Tips' article).

Then copy this php.ini file to the following folders of your store:

a) the root folder of your web store

b) the root folder of your store's admin section, usually called 'admin/'

Test your PAPs installation with a browser. It should now be working.
