Error: "Error type: Could not find a valid session key."
This is similar to a number of other times people have run into this problem, but I've looked through all of those here on StackExchange, have tried those things, and have not found any luck yet.
When donating via a contribution page, receive an HTTP 500 error instead of the thank-you page and thank-you email receipt. The contribution record is logged into the database, but the website can't go to the right page because the session key is invalid. It is going to https://example.org/civicrm/?page=CiviCRM&q=civicrm/contribute/transact
This used to work fine. Recently moved to new server, updated civicrm.settings.php and the Directories and Resource URLs pages appropriately.
Any ideas? Am I missing something really obvious?
I could always go up to Stripe 5.2 and CiviCRM 5.3, but was hoping to be able to fix it in this version.
