Troubleshooting

Whilst we are proud of our reputation as a very reliable method of backing up and migrating websites, sometimes our customers encounter issues. This guide aims to help you to resolve those issues.

Installing the plugin:

The free plugin that is available on WordPress is required for all extensions. Please make sure that you have the plugin installed.
If you need instructions on installing the base plugin, please see wordpress.org and for extensions, please see https://help.servmask.com/section/install/

Taking a backup or export of your site

A backup and an export are the same processes. Exporting the contents of your WordPress site with the plugin creates a .wpress file. This archive is the backup that you can keep in case you need it or the file that you can import to a new site to migrate.
The backups page of the plugin will show any backups that you have on your server. Creating a backup on the server from this page will take you to the exports page, where you will select where you want to back up to.

Issues with backups

  • you need to have enough space on your server to store the backup file, which means more free space than the size of your backup file that will be created.
  • you need to have permissions on wp-content that will allow you to write the backup to the folder. We recommend that you have 775 recursively on wp-content
  • If you have a site that is larger than 2GB, you need to have 64 bit PHP due to the limitation of 32 bit PHP file size. Please also check our list of unsupported hosting providers for those with limitations
  • you need to have sufficient memory limit on your server to process the backup. The minimum recommended is having memory_limit set to 256M (although small sites can get away with less).
  • If you have used other backup plugins, you might find that you are backing up your backups and creating huge files. If you file seems larger than it should be, check that you have removed all backups from your hosting server.
  • Transients, large database tables and incompatible plugins can also cause issues. In this case, please contact support for assistance.

With issues on export or import, it can be useful to look at the error log that can be found at wp-content/plugins/all-in-one-wp-migration/storage/error.log

Downloading a backup

  • In some cases, poor internet connections, server restrictions or browser issues can mean that the download from the download button on the plugin can fail. You can try a different browser, but If this happens, we recommend that you download through the file manager in your hosting or using an FTP client. You will find the backups in wp-content/ai1wm-backups

Migrating your website or restoring a backup

Issues with restoring a backup

The file that you import must be a .wpress file that was created by our plugin. We recommend a new WordPress install to ensure that the install is clean, but this is not essential.

  • If your import page on the plugin doesn’t look right, there might be an issue with your site and home URL
  • Whilst the All-in-One WP migration plugin is fully compatible with older and new PHP versions, the content of your website (themes, plugins) may not be. Check that the PHP version of your exporting and importing sites are not in conflict. More information here.
  • Use our Traktor tool to check the integrity of your backup and look at the contents if you want to check integrity before import
  • you need to have enough space on your server to store the backup file and then recreate the website on your site. You should have enough space to store your site 2.5 times.
  • you need to have permissions on wp-content that will allow you to write to the wp-content folder. We recommend that you have 775 recursively on wp-content
  • you need to have sufficient memory limit on your server to process the restore. The minimum recommended is having memory_limit set to 256M (although small sites can get away with less and larger sites may need more).
  • If the restore process stalls or is taking too long, follow this guide
  • Sometimes plugins can conflict during import. You can check the located at /wp-content/plugins/all-in-one-wp-migration/storage/error.log to see if there are any issues.
  • If your website is not working after import, you can see this guide.

You can also look at the common issues on this support site or contact the support team if these recommendations don’t help.

        Hi Pim – I’m searching for a resolution for this error for All in One WP Migration as well. We are in the process of upgrading to PHP 7.2 and the 9 errors listed by Parveen above are exactly what we are seeing on our 9 websites as well. We are currently on PHP 7.0. Is there a solution for these errors?

          Hi Nedra,

          PHP Compatibility Checker plugin is not maintained and we do not recommend it to be used.
          Every plugin that supports multiple versions of PHP will display a similar output from the above plugin.
          All-in-One WP Migration supports all versions of PHP from 5.2 up to 7.3 and can be used without issues on any of these PHP versions.

    all-in-one ftp extension,

    I keep getting an error activating it.
    Plugin could not be activated because it triggered a fatal error.

    Fatal error: require_once(): Failed opening required ‘/home/elysianwebdev/elysianatflamingo.com/wp-content/plugins/all-in-one-wp-migration-ftp-extension/loader.php’ (include_path=’.:/usr/local/lib/php:/usr/local/php5/lib/pear’) in /home/elysianwebdev/elysianatflamingo.com/wp-content/plugins/all-in-one-wp-migration-ftp-extension/all-in-one-wp-migration-ftp-extension.php on line 58

    I have also tried uploading it via FTP, which sometimes works, but not in this case, I see it in the Plugin folder,

    thanks1

      Hi Tony,

      Could you download a new copy of FTP Extension from the download link and re-install?
      Please let me know if this resolves the issue.

    Hi,

    Is there a way to open a .wpress file on a Windows PC so I can grab some image files out of it? I tried renaming the file to a .zip but it didn’t work. Or do you have a tool to be able to crack open the wpress file please?

    Cheers,
    Rick

    I have the paid unlimited extension and it is activated and i still get this error

    “Restore” functionality has been moved to a paid extension. Get it here or download the backup and then use “Import from file”.

      Could you make sure that the following plugins are the latest versions;
      1. All in One WP Migration version 6.79
      2. All in One WP Migration Unlimited Extension version 2.22

    hi , i have paid extension , i keep getting this error : https://imgur.com/a/DkbW4kQ

    i have checked in my cpanel and also my hosting support have checked on this and this is their reply :

    Hello,

    Thank you for your patience up to now.

    We have reviewed the issue and attempted to fix it, but due to some coding issue of the plugin you are using, we were unable to resolve it. For some reason, the exports are trying to be saved in “/home/dubaiaudhb/check” server path, instead of saving it to the actual document root of the website. Please contact the vendor of the plugin to assist you further with resolving the bug, we do not provide web development services and would be unable to assist further.

    Best Regards,

    Support Team Supervisor
    TMDHosting.com

    how do i resolve this issue

    1. Pim J. Iliev

      Hi Michael,

      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?
      Please reach out to support@servmask.com for premium extension support.

    Hello,
    My backup hangs up indefinitely during Export at the “Retrieving list of WordPress Files…” stage.
    I have turned off all plugins and removed W3TotalCache plugin. The error log had shown some issues with ‘file doesn’t exist” and W3T.
    But the issue persists.
    The site is relatively small and not complex at all. There is well enough server space for the file.
    PHP Memory is set to 256M
    Max execution time to 180
    I have successfully used the plugin on other sites on this server.
    I’m baffled

    hello I have the same error as the previous man:

    Unable to import
    ai1wm_compatibility is not defined

    I already have the latest version of All in One WP Migration, I also have the latest version of the extension. What could be the problem?
