[Plugin: Contact Form 7 to Database Extension] Unexpected Output During Activation

  • I’m getting this error when activating the plugin:

    “The plugin generated 1603 characters of unexpected output during activation. If you notice “headers already sent” messages, problems with syndication feeds or other issues, try deactivating or removing this plugin.”

    I’m not getting the errors listed above, but at the same time, no form submissions are being saved to the database. (I am using this with Fast Secure Contact Form)

    In fact, looking at the database itself, I can’t see any new tables created – should there be some?

    I’ve deactivated, deleted, reinstalled and installed the plugin more than once. I’ve also checked my PHP version, and I am on PHP Version 5.2.17.

    Do you have any suggestions?

    Thank you.

    I think the problem is that the plugin is unable to create a table in your DB when it activates. It tries to print out an error message, but cannot because this is at a point in WP has not yet started generating the page content.

    It could be a permissions issue related to your MySQL connection. Can the login that WP is using to connect to MySQL create a table?

    You could try logging into MySQL with the same login that your WP is set up to use (in your wp-config.php file), and try creating the table manually: 

    CREATE TABLE IF NOT EXISTS wp_cf7dbplugin_submits (
            submit_time DECIMAL(16,4) NOT NULL,
            form_name VARCHAR(127) CHARACTER SET utf8,
            field_name VARCHAR(127) CHARACTER SET utf8,
            field_value LONGTEXT CHARACTER SET utf8,
            field_order INTEGER,
            file LONGBLOB)

    Fix any permission issue, then try re-activation of the plugin.

    You hit the nail on the head there, I updated the MySQL user permissions to be able to create a table, so now that appears in the database. Interestingly, the Custom Contact Forms plugin created tables – and apparently that should not have been possible with the previous permissions. Curious.

    Just as an FYI, a reactivation didn’t seem to insert the tables into the database, I had to delete the plugin, reinstall and then activate.

    On testing, data posted in the form is now saved in the database – brilliant!

    However, despite that success, I am still received the error notification, although now with less characters of unexpected output:

    “The plugin generated 1010 characters of unexpected output during activation. If you notice “headers already sent” messages, problems with syndication feeds or other issues, try deactivating or removing this plugin.”

    Any suggestions as to what it might be? If not I will just leave it as to all appearances, it seems to be working fine.

    It might be more useful if these characters of unexpected output are saved in an error log file, or at least displayed somewhere. But I supposed this might be a WordPress thing rather than something you could do?

    Thanks for your help.
