Hi Jim,

yes, you can use Paypal Pro Registration form without having Paypal Pro account.
You need to enable Free registrations in s2Member General Settings.
I’m using this shortcode: [s2Member-Pro-PayPal-Form register="1" level="0" ccaps="" desc="" tp="0" tt="D" captcha="white" /]

I hope I could help.
Cheers,
Attila

Hi,
I have experienced the same problem and it seems, there is a conflict between s2Member and WPML plugins.
WPML adds permalink_filters in file sitepress.class.php:
// posts and pages links filters
add_filter(‘post_link’, array($this, ‘permalink_filter’),1,2);
add_filter(‘post_type_link’, array($this, ‘permalink_filter’),1,2);
add_filter(‘page_link’, array($this, ‘permalink_filter’),1,2);

and in the filter itself there is a database query, which causes the error:

function permalink_filter($p, $pid){
global $wpdb;
if(is_object($pid)){
$pid = $pid->ID;
}
$post_type = $wpdb->get_var(“SELECT post_type FROM {$wpdb->posts} WHERE ID={$pid}”);

I suppose, the problem is that $pid is not set … its value gets lost somewhere in the chain of functions listed also in the error message.

For me, this error occured only, when I saved a page in the editor.

A temporary solution is to deactivate s2Member and then activate it again. I suspect some caching problem as it is also in the error message: c_ws_plugin__s2member_cache::cached_page_links

I wrote these details to help s2Member team to figure out the problem…

Cheers,
Attila
