As you can see in the image below, when the InfoPath web part is placed on the SharePoint page (SharePoint 2013), it moves the page content area of the center.
This has happened on multiple pages. I can't seem to find any information about why this is happening.
Any help would be appreciated.
This is somehow a bug in SharePoint 2013 (check here). A quick resolution would be to add the following CSS to the page (in a hidden Content Editor WebPart or a Script Editor WebPart):
#sideNavBox {
display: none;
}
