# DEV UPDATE: Ajax uploads enabled by default

 * As of version 2.3.1 the plugin option “Enable Ajax file uploads” is enabled by
   default.
 * Any users that saved their settings with 2.3.0 installed will have to enable 
   this option, but new users (or those updating from older versions) will not.
 * This setting fixes the problem of hosting providers blocking save and sync operations.
   In short, sending PO data to the server is now done as a Multipart file upload
   and not as a regular form field. The latter causes some security software to 
   block the operation, especially when the data is large. Often this produced [incoherent error messages](https://localise.biz/wordpress/plugin/faqs/ajax-errors)
   and variety of irrelevant HTTP status codes. For more history, see [this previously pinned topic](https://wordpress.org/support/topic/dev-update-saving-large-po-files/).
 * It’s entirely possible that file uploads will now cause a different set of problems,
   in which case the feature can be disabled. The upload is done via Ajax (which
   means a modern browser is required) and on the back end the data handled as a
   [PHP upload](https://www.php.net/manual/en/features.file-upload.php) as are any
   file uploads in WordPress.
 * The new option was added in [2.3.0](https://github.com/loco/wp-loco/releases/tag/2.3.0)
   as an experimental feature, but was not enabled by default. I’ve waited three
   months for feedback on this and nobody has reported any new problems with the
   uploads. In all cases, users reported that it fixed their security issue.
