Support Undefined index error

[Movie Prop Sites]

I am getting the following error on my server several times a day. Any idea what is causing this?


ErrorException: Undefined index: xfa_fss_paypal - library/XenForo/Visitor.php:678

Hum odd, this is supposed to be a column existing in the database.

Do you have a column names xfa_fss_paypal in your xf_user database table ?

Are non registered users allowed to purchase ?

 

[Movie Prop Sites]

Yes.


Yes.

Hum, are you able to reach the following page when not logged in:
https://xxx/forums/threads/arkham-origins-action-figure-lot.296156/xfa-fss-purchase"

Replace xxx by the url of your forum.

https://xxx/forums/threads/arkham-origins-action-figure-lot.296156/xfa-fss-purchase"

Replace xxx by the url of your forum.

When I go to this link, it immediately redirects and takes me to paypal. Does that mean it is a permissions issue?

 

[Clement]

Ok but where you connected before in that browser ? Coz that wouldn't be not loggedin.

 

[Movie Prop Sites]

Tried it from a completely new browser when it wasn't logged in. Came to a page that simply said "Not for Sale."

 

[Clement]

When you used that url ?

Well then I don't see how this error you have is triggered, this is the only idea I have.
If non logged in users are not allowed to buy then it's impossible that the error is popped out by an unknown account.

I realized the error. That seller had already sold the item.

Tried another one.

In a browser I have not been logged in on, this link takes me directly to paypal, so even though unregistered members are not able to buy... if they click the link it is taking them to paypal.

 

[Clement]

How did you realize ?
Are you able to reproduce ?

 

[Movie Prop Sites]

When you said it was impossible, I went back and looked at the item for sale that you had asked me to test.

https://www.therpf.com/forums/threads/arkham-origins-action-figure-lot.296156/

It was already sold.

When I look at any of the sales posts without being logged in, the buy button is greyed out and can't be clicked but if you know to add "/xfa-fss-purchase" to the end of the url of the for sale thread, it takes you directly to paypal to purchase.

 

[Clement]

Hum.
Yeah, hard to solve without being able to reproduce.

 

[Movie Prop Sites]

Hum.
Yeah, hard to solve without being able to reproduce.

If you click this link, what happens?

[Clement]

I get redirected to paypal

 

[Movie Prop Sites]

I get redirected to paypal

Correct. Which should not happen because you aren't a member or logged in. That is the problem. If someone knows the link, whether they are a member or not, they are sent to paypal, which isn't a good thing. Can this be stopped?

 

[Clement]

Oh so that triggers the error ?

 

[Movie Prop Sites]

Well... I thought so, but now in testing further, whether you are logged out or in, if you click on a buy it now link, the site generates that error... so there are two issues;

First, clicking the link creates that error.

Second, a non-user who figures out the link can technically side-step the permissions.

 

[Clement]

Clicking when logged in does generate the error ?
Are you sure about that ?

I was thinking it came from the second issue.
