This thread is resolved. Here is a description of the problem and solution.
Problem:
You are trying to embed a Google map on your page, but the visual box has disappeared, leaving only the HTML version visible in the Classic Translation Editor (CTE). Previously, a code change involving the removal of 'iframe' from a blacklist in a specific PHP file resolved the issue, but the code has disappeared after an update.
Solution:
If you're experiencing this issue, we recommend you edit the file at
wp-content/plugins/sitepress-multilingual-cms/classes/translation-jobs/ExtraFieldDataInEditor.php
. Previously, the modification was made at line 155, but due to updates, it has now moved to line 199. You should locate the blacklist array and modify it by removing 'iframe' from it, changing the line from:
$black_list = ['script', 'style', 'iframe'];
to
$black_list = ['script', 'style'];
This change should restore the visual box in the CTE.
