[Resolved] Error while editing the posting in secondary languages

Problem:
The client is experiencing an issue where the Elementor editor loads fine for the default language (English) but gets stuck on the loading screen when trying to edit translations manually.

Solution:
First, we recommended the following steps to ensure that the translation is not being hindered by the use of different translation editors:
1) Create a Header Template
2) Duplicate it to secondary languages
3) Switch to a secondary language via the Dashboard language switcher of the top header
4) Open the Duplicated Header Template for edit
5) Click on Translate Independently button
6) Update the Template from Elementor Editor
7) Save the changes
For more details, please refer to our documentation on using different translation editors for different pages.

If the issue persists, it may be due to a conflict with the rewrite rules in the .htaccess file. We found that making the following changes to the .htaccess file resolved the issue on a staging site:

From

#Force trailing slash
<ifmodule mod_rewrite.c>
	RewriteCond %{REQUEST_URI} /+[^\.]+$ 
        RewriteCond %{REQUEST_URI} !^/wp-json
	RewriteRule ^(.+[^/])$ %{REQUEST_URI}/ [R=301,L]
</ifmodule>

RewriteEngine on
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1 [R=301,L]

To

# Force trailing slash
#<ifmodule mod_rewrite.c>
#	RewriteCond %{REQUEST_URI} /+[^\.]+$ 
#        RewriteCond %{REQUEST_URI} !^/wp-json
#	RewriteRule ^(.+[^/])$ %{REQUEST_URI}/ [R=301,L]
#</ifmodule>

#RewriteEngine on
#RewriteCond %{HTTP:X-Forwarded-Proto} !https
#RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1 [R=301,L]
