# Error message when testing memberships: “Expected one PaymentProcessor but found 0”

we are now trying to test the membership signups which includes recurring payments. I've gone through all the steps on the contribution pages and have not seen any errors there (except that no thank you email was sent, but this may be a separate issue from this one)

However once I go to "Memberships" -> "Find Memberships", choosing "Yes" for "Membership is a test", and clicking on "Search" I get this error:

Sorry but we are not able to provide this at the moment. Expected one PaymentProcessor but found 0

Output from /sites/default/files/civicrm/ConfigAndLog:

Mar 02 18:51:27  [info] \$backTrace = #0 /home/peoplesfund/www/www/sites/all/modules/civicrm/CRM/Core/Error.php(451): CRM_Core_Error::backtrace("backTrace", TRUE)
#1 /home/peoplesfund/www/www/sites/all/modules/civicrm/CRM/Core/Invoke.php(55): CRM_Core_Error::handleUnhandledException(Object(CiviCRM_API3_Exception))
#2 /home/peoplesfund/www/www/sites/all/modules/civicrm/drupal/civicrm.module(448): CRM_Core_Invoke::invoke((Array:3))
#3 [internal function](): civicrm_invoke("member", "search")
#6 {main}


(Entire output is not shown because a huge code mass is printed. I can provide this if needed though in a file)

I've also tried enabling debugging but the same error screen is shown

There is no problem when searching if we have chosen "No" for "Membership is a test", this will (instead of the error message) produce a list of real members that we have

Does anyone know what we can do to solve this problem? Is it likely that this will cause problems for the live contribution pages in the future (even if that is not the case right now?)

Grateful for help and with kind regards, Tord
