OTGS Installer

This release makes site-key registration hold up when wpml.org throttles or times out, stops needless subscription checks, and fixes what the Activate & Update page shows when the products feed cannot be reached.

Site key and registration

• When wpml.org answers that your site key is invalid, the site no longer keeps that key as its subscription key and acts as registered; it shows the registration box instead.
• A site key defined in wp-config.php keeps its registration when wpml.org only throttles or times out.
• On a network where sites define different keys, one key is registered and the site with the other key is named, instead of the sites re-registering the key back and forth.
• On multisite, the WPML subscription is stored in the network settings only.
• Users with WPML's Support capability can refresh the site key.

Subscription checks and page speed

• The subscription is read from wpml.org once per request, and after a failed or refused answer the site waits before asking again, instead of revalidating the key many times a second.
• Concurrent calls to the refresh route validate the key once, and the route answers "Not stale" with a success status when there is nothing to refresh.
• Writing the Installer log no longer takes a database lock, so servers that refuse named locks, such as a Percona cluster in strict mode, show no database error.

Activate & Update page

• The registration box keeps its controls in every account state, instead of rendering empty.
• When the WPML products feed cannot be reached, your WPML products stay listed.
• Switching the update channel refreshes the list and installs nothing, and after switching back to Production the download gives you the production version.
• A plugin's release notes show that plugin's notes, not another plugin's.
• A Blog plan sees the plugins the CMS plan adds as rows it cannot download, with a purchase link, and each row's checkbox is named for screen readers.

Errors and warnings fixed

• No fatal error on Activate & Update when no product matches the subscription type.
• No fatal error on the Commercial tab when re-registering a site key, and the expiry warning reads the subscription type when no subscription id is passed.
• Stored settings are read in their own format, so a site moved between servers no longer hits a fatal error.
• Plugin checks and update screens skip a product that has no download row, so the Plugins page logs no PHP notices when the feeds disagree.
• The plugin update entry carries the required WordPress version, so WP-CLI prints no warning on every plugin list.
• Plugins no longer show "Not tested with your current version of WordPress" on WordPress point releases.

Also in this release

• Log entries written by concurrent requests are all kept.
• The "communication error details" link in connection notices opens the Installer log in WPML's Support tools.

Security

• Security hardening of the plugin download request.

This release makes site-key activation and plugin recommendations more reliable, fixes the Add Themes tab, adds missing translations, and includes a security update.

Site key and activation

• Fixed a critical error on the WPML → Activate & Update page that occurred when your stored subscription had no product data.
• Fixed a fatal error on admin screens on PHP 8.4 caused by an incorrectly declared parameter.
• Added a clear message when your site key has been deleted, instead of the confusing "Development Site" banner.
• Made a failed products check show one clear notice instead of leaving the screen without feedback.

Plugin recommendations and Add Themes

• Fixed the commercial tab no longer preselecting recommended plugins when WPML core is inactive.
• Stopped the Installer from showing WPML add-on recommendations when WPML itself is not active.
• Fixed the Add Themes tab, which had stopped working.

Translations

• Added WPML plugin translations for supported language variants so you no longer see English text fall back in.
• Localized the lead descriptions shown in the Installer.

Also in 5.0.0
