I see you mention the optimization has remained on the same step for more than 24 hours. We’d first like to confirm that WordPress is able to process background tasks correctly.
Please go to Tools → Site Health → Status and check for any errors related to:
Loopback requests
Scheduled events
In particular, please look for messages such as:
“Your site could not complete a loopback request”
“A scheduled event has failed”
“A scheduled event is late”
Please also check your wp-config.php file for the following setting: define( 'DISABLE_WP_CRON', true );
If DISABLE_WP_CRON is set to true , please confirm with your hosting provider that a server-level cron job is configured to invoke wp-cron.php regularly.
Please also check if you have any PHP or server error-log entries generated since the update, especially entries mentioning TranslatePress, admin-ajax.php , SQL errors, memory limits, or execution timeouts.
These checks will help us determine whether background processing is preventing the optimization from progressing.
Please also let me know on what version of TranslatePress Multilingual you are currently.
Thank you for your response and for the screenshots!
Could you please let us know if you’re using any security plugin on your site, such as Wordfence, or any server-side security measures, or Basic Auth protection?
This WP 2FA should not interfere with the TranslatePress background optimization, so you can keep it enabled.
However, the HTTP 403 loopback error indicates that a firewall or server-side security rule is blocking requests made by your website to itself. Since the site uses Cloudflare, please check Cloudflare’s Security Events for blocked requests to:
/wp-admin/admin-ajax.php
/wp-cron.php
You may need to ask your hosting provider to identify the server’s outbound IP address and allowlist it in Cloudflare or the server firewall. Once the loopback error no longer appears under Tools → Site Health, please try the TranslatePress optimization again. Once the optimization process completes successfully, you will no longer need to keep that allowlist entry in place, as it is only required for the duration of the process itself.
