Background of the issue:
I am trying to open the wp-admin/update-core.php page on my site lien caché to update the WPML plugin, but I encounter issues. The page displays messy code, and I cannot update the plugin manually. I also see an error related to wp-json/wpml/v1/dashboard.8304e558.css.map with a 404 status code.
Symptoms:
Unable to open the update page and manually install the plugin. Encountering HTTP Error: Status Code 404 for wp-json/wpml/v1/dashboard.8304e558.css.map.
Questions:
Why is the wp-admin/update-core.php page displaying messy code?
How can I manually update the WPML plugin?
What does the HTTP Error: Status Code 404 for wp-json/wpml/v1/dashboard.8304e558.css.map mean?
