I recently upgraded my 7.x maxbulk mailer, now it does not recognise the previously stored lists in my mysql database. The lists are there and intact, but do not appear in drop down list under recipients tag.

When I create a new list and add one email address, I get an error, but when I check the mysl database the email appears to have been stored....

Are you sure the MLM URL is correct in the MaxBulk Mailer preferences?

thanks for the suggestion, it was bang on the money. Wrong url, everything now working fine.
