Hi, Thank you for uploading the phpinfo file.
My guess was right. Your PHP is not recognizing the https protocol.
To fix it, please apply the update I made.

----------------------------------------------------
To apply the update,

1) First, back up the entire script folder( the one that you are
currently using in your web site ) so you can restore the script
in case you accidentally delete files/folders in the following steps.

2) Find the following 3 folders in the script folder:

admin
cn
lib

3) Rename each folder as shown below:

Rename admin to admin-old
Rename cn to cn-old
Rename lib to lib-old

4) Download the following zip file:
https://www.phpkobo.com/demo/ajax-like-patch/patch.zip

5) Unzip the zip file and find the following 3 folders:

admin
cn
lib

6) Upload those 3 folders into the script folder in your website.

7) Confirm you have the following 6 folders in the script folder:

admin
admin-old
cn
cn-old
lib
lib-old
----------------------------------------------------

That's it! The update is now completed!
