Support » Plugin: WordPress Backup to Dropbox » Error Specified key was too long; max key length is 1000 bytes

  • Hello,

    It’s happening the error described below after I activate the plugin and click Settings.

    Therefore, because of this error I can not even get to allow connection to my dropbox.

    Could anyone help me, please?

    Thank you.

  • I have the same problem – can’t configure wpb2d because of that issue. All other plugins (except jetpack & akismet) disabled. It’s running fine on my other WP sites.

    Looking at the logs, the only additional info is that “Specified key was too long; max key length is 1000 bytes” is followed by “for query CREATE TABLE” and the 3 table names, “wpb2d_processed_files”, “wpb2d_processed_dbtables”, and “wpb2d_excluded_files”.

    Temporarily, to make wpb2d work, I edited wp-backup-to-dropbox.php and changed file varchar(255) NOT NULL to file varchar(200) NOT NULL in function wpb2d_install() {}.

    I think you’d have a problem with this if your file paths are going to be more than 200 characters in length (e.g. some shared hosting) but aside from that, everything else should work fine.

    Thanks..! This works fine..!
    Just make sure you change all the 255 to 200 in the php file (there are usually 4nos of 255 in the code)

    Thanks. Issue still exists so will use this workaround. Would be nice to have a proper fix at some point 🙂
