plz check why this.ㅠㅠ
Can you please try deactivating the third party plugins and switching to the main default child theme and check the issue is appearing there also ?
If issue is not replicable in main theme then please check custmizations in your child theme .
I fixed this issue.
The file that child theme/templates/course/frontcx.php made issue.
Because it is different past files.
Thanks.
