[Resolved] Homepage stays as

1. Go to WPML -> Translation Management -> Translation Jobs and cancel the in progress job. If there is no in progress job, continue to the next steps.
2. Edit the default page. Make any small change and update the page.
3. Go to WPML -> Translation Management and send this page to the translation basket. Tick the checkbox, scroll down and click translate, then you will see the translation basket tab.
4. Click the translation basket and send the page to yourself as a translator.
5. Go to WPML -> Translations and take and translate the page. Save the translation 100% and then let's see if the correct content shows.

Please let me know if this resolves the issue.

Let's enable the debug log to see if there are any background errors happening.

WordPress includes a debug mode that helps reveal PHP problems. Let's enable this and see if there are any errors we can locate.

To enable it, open your wp-config.php file and look for

define('WP_DEBUG', false);

Change it to:

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

In this case the errors will be saved to a debug.log log file inside the /wp-content/directory.

The wp-config.php is located in your WordPress root directory. It’s the same file where the database configuration settings are. You will have to access it by FTP or SFTP in order to edit it.
If you open wp-config.php and that define statement is not there, you can add it right before this line:

/* That's all, stop editing! Happy blogging. */

Please note that you’ll see everything, not only related to our Plugins. This will most likely include messages from other plugins, your theme, and sometimes even WordPress core. The messages appear all over the place.
Sometimes they appear right on top, but they can also appear in the middle of the page.

After enabling the debug mode, please try to replicate the issue. Navigate to the page where the error message being displayed. The errors will be either displayed on the screen or logged in the debug.log log file inside the /wp-content/directory.

Paste the latest lines here. No need to paste the entire log file, just 50 lines or so will do. Please censor any sensitive information.

I'd also like to login and see if I can test this, with the debug log enabled, to look for errors. Is it okay for me to install a file management plugin? If so, please share credentials using the private fields in the next reply and I can look further into this for you.

I am no longer able to login, I get the error message "Error: The username wpml is not registered on this site. If you are unsure of your username, try your email address instead. I have marked the next reply as private so that you can share updated credentials. Thanks.
