Hi,
Thank you very much for the details, I tried to log-in with the details, but I am getting this message, when trying to access the back-end URL: https://i.imgur.com/zfuA9kj.png
I think I still see the problem. The extra CSS class “asp_es_1” is placed on the wrong elementor widget. I am seeing the class name on the search block: https://i.imgur.com/SGGp4p4.png
That is not correct, make sure to remove that class from there, and place it on the posts widget: https://i.imgur.com/Lvq6zvF.png
That should resolve the issue 🙂
