Guest Mode failed to test

this most likely due to some security plugin blocked this request, does the file actually exist on your file system ?

I detailed the problem description and added the Report number.
guest.vary.php is definitely in the litespeed-cache directory, and I have deleted the security plugin:aiowps. However, when accessing guest.vary.php, 404 is still returned.

yeah sorry , seems I replied before you edited it

if file exists as you can see in FTP or file manager, and it can not be accessed as return 404 , that means something in your server (apache conf or htaccess) rewrote that request to 404

check if you see any .htaccess in ./wp-content/ and /wp-content/plugin/ and what is the content

if no htaccess on these 2 dir , then sadly I am afraid there is nothing more I can do about it , this will need your hosting provider to check for you , as they have server access.

Thank qtwrk for your prompt reply!

.htaccess in ./wp-content/:

<FilesMatch ".(py|exe|phtml|php|PHP|Php|PHp|pHp|pHP|phP|PhP|php5|suspected)$">
Order allow,deny
Deny from all
</FilesMatch>

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . index.php [L]
</IfModule>

There is no .htaccess file in the /wp-content/plugins/

Thanks for the reminder,

I modified the .htaccess file in ./wp-content/ ，now I can access guest.vary.php and Guest Mode testing result: Guest Mode passed testing

Thanks again!

try remove or rename /wp-content/.htaccess , or at least comment out this section.

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . index.php [L]
</IfModule>
