Blog post alignment issue

Hi guys,

I am stuck with the blog post alignment issue, I am using the default theme, and as you can see on the mobile version the text went all the way to the far left on the screen, I tried to make the width 1000 but that did not fix it, I even create a column, i put all the text on it and changed the padding to M but still not fixed! this happened after the last update not sure if it was the wp update or some pluggins update.

Please let me know how can i fix this issue, many thanks in advance.

Kind regards.
