Hi,
We also have several client sites unable to complete the migration preview with “WordPress database error Deadlock” errors showing up in the error log.
PHP: 7.4.30 / WP 6.1.1 / Events Calendar 6.0.4 / Pro 6.0.3
After some digging we disabled the migration preview by inserting the following filter:
add_filter( 'tec_events_custom_tables_v1_db_transactions_supported', function(){ return false; } );
Our sites now skip the migration preview but are able to complete the migration process itself seemingly without issues.
Please let me know if there’s somewhere else to raise/share this issue.
