      Hi Ibrahim
      Please make sure that you have the free All-in-One WP migration plugin installed. The base plugin is required for the unlimited extension to work.

    Hi, I’ve done this process multiple times successfully but I’ve been getting an error recently saying that my version is outdated. Every time I attempt to export or import to file, the file fails to download. I’ve looked for an update online but couldn’t find anything. Any thoughts?

    1. Lesley Arnold

      Hi Kimberley
      Thanks for getting in touch.
      If you need to update the extension, please go to the plugins page on the WordPress dashboard and find the extension. You’ll see a link there – “check for updates”
      Please install any pending updates
      Kind regards


    I have a problem, I’m working in Local, during the restore process, when restoring the database, everything stops at 15% and it does not progress anymore.
    I use it to restore my website which is online to the local site


    I have a problem saving my online website. I have “Out of disk” error message message

    “Out of disk space. Unable to write content to file. File: /home/***/www/wp-content/plugins/all-in-one-wp-migration/storage/sbev2lc39ydi/www.***.com-20180722-140701-874.wpress

      We are sorry to hear that you are having issues.
      The plugin needs to have space and access to be able to function on your site.
      Can you check that you have set permissions on your wp-content directory to 775 recursively and that you have enough disk space on the server to save the site 2.5 times?

    I have installed both the free plugin and the unlimited extension plugin and I am still getting the message “Your file exceeds the maximum upload size for this site: 32 MB”.

    Suggestions for next steps?

      Hi Loren,

      Could you make sure that the free version and Unlimited Extension are up to date (version 6.79 and 2.22, respectively)?

    I have the paid version.

    After migration, even after using my login and password of the old site, I ‘am redirected to the same login page.

    what is the issue?
