[Chiuso] Saving or updating posts takes over 1 minute after latest WPML update (proxy_interceptor.js delay)

Hi there,

I’m Paola from WPML Support — thanks for your detailed explanation.

This kind of delay during post updates (with wpml-proxy-interceptor.js) usually happens when the REST requests used by WPML to synchronize translation data take too long to respond — often due to a conflict or excessive data loading in the background.

To narrow it down, could you please try the following steps?
- Create a staging copy of your site (if possible).
- Deactivate all plugins except WPML and its add-ons, and switch to a default theme (like Twenty Twenty-Five).
- Try editing a post again and check if the delay persists.

If it works fine, reactivate the plugins one by one to find which one causes the slowdown.

Also, please enable the WordPress debug log so we can see if any PHP warnings appear during the save process:

define( 'WP_DEBUG', true );
define( 'WP_DEBUG_LOG', true );
define( 'WP_DEBUG_DISPLAY', false );

Then, try saving a post again and share the log file from /wp-content/debug.log.

Once we have that information, we’ll be able to determine whether the delay comes from WPML itself or an interaction with another plugin or script.

Hi there,

You can copy the error logs from your debug.log file, paste them on https://pastebin.com/ , and then send me the link here.

Thank you.

Hi!

Thank you for the detailed report and for running all those WP-CLI tests — that really helps narrow things down.

Please try these quick steps so we can confirm where the bottleneck is:

1. Go to WPML → Support → Troubleshooting and click on:
Clear WPML cache, Remove ghost entries from translation tables, and Fix element_type collation.

3. In WPML → Settings, make sure only the fields you actually need are set to “Translate”.

3. Check with your hosting that outgoing requests to WPML domains (like api.wpml.org, ate.wpml.org, wpml.org) are not blocked by a firewall or proxy.

If the problem persists, I would like to request temporary access (wp-admin and FTP) to your site to take a better look at the issue. You will find the needed fields for this below the comment area when you log in to leave your next reply. The information you will enter is private which means only you and I can see and have access to it.

**IMPORTANT**
- Please make a backup of the site files and database before providing us access.
- If you do not see the wp-admin/FTP fields this means your post & website login details will be made PUBLIC. DO NOT post your website details unless you see the required wp-admin/FTP fields. If you do not, please ask me to enable the private box.
