Hi our site is no longer responsive, tried reverting to an earlier backup but still the same issues. The columns are no longer stacking like they should.
I know how to style for responsive, pages were already responsive. There is something causing an issue across the whole site, the columns are not stacking like they used to.
Please deactivate all the 3rd party plugins and activate only theme-required plugins on the site and then check the issue. I am sure your issue will be solved. Then Activate the 3rd party plugins one by one and check which plugin is creating the issue for you.
Otherwise, if the issue still exists then keep the 3rd party plugins deactivated and let me know I will further check on your site and give you a possible solution.
