Good morning. Can you help me. I can’t get EE out of maintenance mode – the database won’t migrate. Have attempted again and again and again…Am on WordPress 4.6.1, EE4, Theme Enfold. Here are the messages in the system. Site is http://www.EDCCOnline.org
Thank you!

Hi Melodie,
The PHP warnings indicate that there’s something that does not belong in this file, /wp-content/themes/enfold-child/functions.php, on line 30. After that’s been fixed, you can re-run the migration.

Hi there,
The above doesn’t help narrow down the problem, although it does show headers are being sent by your child themes functions.php file:
headers already sent (output started at /wp-content/themes/enfold-child/functions.php:30)
If you check within your themes functions.php file what is shown on line 30?
Do you have access to the servers error logs? If so are any errors shown from EE there?
Or you could try temporarily switching to one of the default themes, run the migration and then switch back and see if that prevents the above.

Thanks for the feedback. Love you guys.
I’ll try swapping the theme tonight and running the migration. If that doesn’t work, I’ll be in touch. Thanks.

Hi Tony,
Tried swapping the theme. No go… the migration is hanging at 10% and I keep getting 0 records migrated over and over and over again.
And it looks like I am getting the same message (see below). What’s next?
Thanks!
Melodie

Event Espresso – Maintenance
As part of the process for updating Event Espresso, your database also needs to be updated. Event Espresso is in COMPLETE MAINTENANCE MODE (both WordPress admin pages and front-end event registration pages are disabled) until you run the database update script. Visit the Maintenance Page to get started, it only takes a moment.

How did you swap the theme?
When you switched themes did you switch to a default theme such as TwentyFifteen or TwentySixteen?
The error being thrown is the same as above so it seems the enfold-child theme was still active.
What appears to be happening is the enfold-child theme is causing a headers already sent notice which is being thrown during the EE ajax request. This means that when EE receives the response back it has no idea what the first part of the response is, this bit:
<br /> <b>Warning</b>: session_start(): Cannot send session cache limiter – headers already sent (output started at /wp-content/themes/enfold-child/functions.php:30) in <b>/wp-content/plugins/event-espresso-core-reg/core/EE_Session.core.php</b> on line <b>401</b><br />
Its simply expecting this:
{\”error\”:false,\”success\”:false,\”notices\”:\”<div id=\\\”espresso-notices\\\”><\\/div>\”,\”content\”:\”\”,\”data\”:{\”records_to_migrate\”:493,\”records_migrated\”:50,\”status\”:\”status_continue\”,\”message\”:\”Migrated 49 records successfully during Event Sub-total line items<br>Migrated 1 records successfully during Pre-tax total line items\”,\”script\”:\”Core Data Migration to version 4.8.0\”,\”template_args\”:{\”admin_page_header\”:\”\”,\”admin_page_content\”:\”\”,\”post_body_content\”:\”\”,\”before_list_table\”:\”\”,\”after_list_table\”:\”\”,\”notices\”:\”<div id=\\\”espresso-notices\\\”><\\/div>\”}},\”isEEajax\”:true}
So as the notice has been thrown in request the migration script has no idea what to do with the data, what to do next etc and loops over.
So in your enfold-child themes functions.php something is causing headers to be sent to the site when it should not. This is often caused by closing the PHP tags and having whitespace afterwards but there are many possible causes.
