Support » Plugin: Optimize Database after Deleting Revisions » Optimize InnoDB too => Problem Exporting MariaDB via PHP My Admin

  • Resolved Plugins and Snippets


    I selected “Optimize InnoDB too” in the settings, now I have an error showing up in PHPMyAdmin when trying to export the MariaDB database.

    Notice in ./export.php#288
    ob_end_clean(): failed to delete buffer. No buffer to delete
    ./export.php#288: ob_end_clean()

    I haven’t seen this error before. It only appeared after I cleaned up a MariaDB database with this plugin. Any idea?

    Hey @pluginsandsnippets,

    No idea why the notice (=warning) suddenly appears…
    Not sure if it has anything to do with my plugin.

    Try (in PHPMyAdmin) to check all tables in the database and run ‘optimize tables’ and see if you get the same warning. My plugin optimizes tables exactly the same way PHPMyAdmin does.

    Let me know.
