We have visited the page and seems everything is fine, can you please elaborate more about the issues with the screenshot so that we can assist you with them.
When I say header I am referring to the header of the Simple Job Postings content. In the code they refer to it as a header. As you can see below in a screenshot the text is squeezed.
We have reviewed your site and found that there is some CSS of row that is conflicting with the header and that CSS is not coming from our plugin.
However to fix the issue kindly replace the following CSS in the path and line number below. Path : simple-job-board\public\css\simple-job-board-public.css CSS: .sjb-page .row { margin-left: -15px; margin-right: -15px; display: block; }
