    Hi. I’m trying to upgrade the data on a site that had TEC deactivated for a long time and is now being reactivated on the current version. I have gone through the steps that you provided on an earlier post and am still stuck on “Loading…” These are my versions:

    • WordPress: 6.8.1
    • PHP: 8.2
    • The Events Calendar: 6.13.1

    I also have the following error in /wp-admin/error_log:

    [30-May-2025 18:37:15 UTC] tribe-canonical-line channel=default level=error source=”TEC\Events\Custom_Tables\V1\Migration\Process_Worker TEC\Events\Custom_Tables\V1\Migration\Process_Worker::undo_event_migration 579″ meta=”{\”started_timestamp\”:1}” phase=preview-prompt

    Thanks.

    I’m experiencing the exact same issue and can provide additional technical details that might help:

    My Environment:

    • WordPress: 6.8.1 (multisite)
    • PHP: 8.1
    • The Events Calendar: 6.13.1
    • ~600 events needing migration

    Same Symptoms:

    • Migration page stuck on “Loading…” indefinitely
    • Browser console shows 404 errors for missing files:
      • /wp-content/plugins/the-events-calendar/src/resources/js/custom-tables-v1/ct1-upgrade.min.js?ver=6.8.1
      • ct1-upgrade.min.css

    Root Cause Discovered: I investigated the plugin files and found that the directory /wp-content/plugins/the-events-calendar/src/resources/js/custom-tables-v1/ is completely empty on both my server AND in a fresh download of TEC 6.13.1 from ww.wp.xz.cn.

    This appears to be a plugin distribution issue – the critical migration files are missing from the 6.13.1 release.

    Impact: This makes migration impossible regardless of server configuration. Multiple users appear to be affected.

    Can the development team verify if the ct1-upgrade files were accidentally omitted from the 6.13.1 distribution?

    Hi @gregf ,

    Thank you for reaching out.

    The Events Calendar version 6.13.1 is quite a big leap for when the migration should have been done. That said and assuming you’re not running the Events Calendar Pro (premium/add-on) plugin, kindly try the following:

    In a staging environment:

    1. Apply this snippet and run it once with Code Snippets plugin (be sure it does not stay activated). This resets the migration that was started or didn’t go through completely.
    2. Uninstall and remove The Events Calendar plugin
    3. Install a previous version of The Events Calendar plugin (preferably version 6.1.1). See Accessing and Installing Older Plugin Versions.
    4. Deactivate all other plugins leaving only The Events Calendar plugin activated
    5. Switch to a default WordPress theme (preferably the twenty-twenty-one theme)
    6. If you have server-level caching, deactivate it (at least temporarily)
    7. Ensure you do not have events in Trash, Ignored, or in Drafts
    8. Increase your WordPress memory limit. You can use this plugin to check your memory usage. If the usage percentage is over 75% when you try to run the migration preview, that’s likely an issue. Increase your memory limit and try again.

    Hi @tristan083,

    Following these steps worked. I think the key was installing the 6.1.1 version before attempting the migration. Thanks for your help.
