Hi,

Thanks for reaching out to us.

The error “1615 Prepared statement needs to be re-prepared” is not related to Joomla 6 itself. It is a MySQL / MariaDB server-level issue.

This usually happens when the database server runs out of internal table cache for prepared statements. In your case, it appears when Joomla tries to update the user’s “last visit” data during logout or on after login

What causes this? • Low MySQL configuration values (table_definition_cache, table_open_cache) • Database server restart or upgrade • Server resource limits • Occasionally corrupted table cache

What you can do

Quick temporary fix: • Restart MySQL from your hosting panel OR • Run FLUSH TABLES; in phpMyAdmin

Proper fix (recommended): Ask your hosting provider to increase: • table_definition_cache • table_open_cache

Typical recommended values are around:

table_definition_cache = 4096 table_open_cache = 4096

If you’re on shared hosting, your provider will need to adjust this.

You can also run “Check and Repair” on your Joomla database tables via phpMyAdmin to rule out table corruption.

Small Fix:

I fix it : In Global Configuration > Server > Database > Database Type : MySQL (PDO) Now no error.

Thanks
