    I am getting failed attempts by PayPal to pass back the IPN response.    It goes to a page that only has a "Save" link and a "Submit" button.   Any thoughts?

    Hi, if you look under Admin / Event Viewer, what specific message or error are you getting? Also, what form completion events are tied to what Paypal process? -- David

    I figured this issue out.   I had my status field for the IPN response as read only.  Changed that and that part worked.  Still no emails triggered. I did receive the following exception:

    Hi Mike,

    Glad you figured out the IPN status field.  There are a few areas to check if emails are not firing:

    1.  Make sure your email event is linked to PayPal Status Completed (Standard) if this is a purchase.  Or for subscriptions, set it to Completed (Subscription Payment)  or Completed (Subscription Sign up).

    2.  Go to Admin, Newsletters and try to send yourself a test email from here.  If you receive this, go to #3.  If you don't receive this, go to Host, Host Settings and check your SMTP settings.  You may have to work with your hosting company to configure this properly.  Our modules use the same email functions as the DNN core so we want to make sure there are no issues here.

    3.  Are you using a PayPal Sandbox account to test?  If you are, please make sure that a) Payment Review is disabled for both personal and business accounts and b) your personal (buyer) account has funds for the transaction.

    4.  Also, for your email event, make sure you select 'any field response' or a specific response.  Don't leave it with 'Select Dynamic Field.'

    Let me know what happens, ok?  Thanks!

    Candace

    This still doesn't work. Although I get a slightly different result than at first, I still get:

    The status does not get updated. The PayPal status is "Failed". The following is retrying prior to a fail:

    Hi Mike,

    So this a situation where the original PayPal transaction failed, right?  Let me put this aside for a moment and try to resolve the email issue first.

    In Admin, Event Viewer, please enable logging for Debug Info.  Try a new test and then go back to Event Viewer. If everything is set right, you should see the different events firing as you receive the IPNs.  Does your email fire off at this point?  What do you see in Event Viewer?

    Thanks!
    Candace

    P.S.  We just released the DF 3.00.30 patch.  Get it from Patches and Hotfixes in Snowcovered so you have the latest build.  Thanks!

    Installed the current patch.  Same result.   I had PowerDNN (my hosting provider) check.   They didn't see anything.  They said if you ned RDP access the could provide it.  The PowerDNN ticket # is GOZ-456208

    It looks like there is a conflict I think... I notice in the error message this:

    DataQ.HttpModules.MobileHandler

    Can you tell me if you have another module that might be causing a problem, when I google this I think something called MobiNuke? Can you disable this and that might help to determine if its a conflict?

    I uninstalled Mobinuke (I hadn't gone far in configuring it). That cleared the issue I had. Thanks!

    Also remember that after unistalling the module in module definitions you will need to delete the following entries from the web.config file :-
     <!--Added by mobiNuke-->

          <addname="MobileHandler"type="DataQ.HttpModules.MobileHandler" />
     
         
          <!--Added by mobiNuke-->
          <addname="MobiNavigationProvider"type="DataQ.NavigationControl.MobiNavigationProvider" />


    It took me a while to figure this out so I thought I would save you the hassle by posting it on here.

    I'm having sort of the same problem.. the PayPal IPN or something isn't allowing the email to be sent out. I can see in the Sandbox IPN status page that they're being sent.. but the dynamic form isn't reading them and/or firing the email off on Completed (Standard).

    I verified that any response is selected on the email completion event. I can see Paypal events in the Event Log.. but no errors.

    I'm new to the whole IPN thing & and dynamic forms.. I'm having a heck of a time finding a good tutorial on IPN handling in dynamic forms.

    HI, can ou first verify that your SMTP settings work by going to Admin / Newsletter and emailing yourself a newsletter first to see if that works? -- David

    I am having similar issues with getting the events to fire after payment from PayPal.

    SMTP is working.

    Here is the debug info I get upon submission.

    Processing Event: - This event is linked to this TXN_TYPE - Payment Complete
    Event Type: PDF
    Txn_type: RedirectSucess
    User Response:
    Event Response:
    Module ID:: 560
    Processing UserID: : 1
    Processing User Name: : HostAdmin
    Server Name: GEORGE

     

    And

     

    Processing Event: - This event is linked to this TXN_TYPE - Confirmation E-mail
    Event Type: Email
    Txn_type: RedirectSucess
    User Response:
    Event Response:
    Module ID:: 560
    Processing UserID: : 1
    Processing User Name: : HostAdmin
    Server Name: GEORGE
