I thought I should switch to production mode from default mode as I got closer to launching my site. As soon as I did that, the formatting of my front-end and admin section got really messed up. The front end is like one column now, almost like a mobile phone version of the site, but not even that nicely styled.
The image below is while still in default mode:
The image above is after the switch to production mode.
The admin section is screwed up also, like it has no formatting at all.
Magento version is 2.2.1. I am also using Porto theme. The Porto people said it looks like a permissions issue, so the last thing I did was follow the directions here, for setting production permissions in a shared hosting environment where you can only have one user. This procedure did not change anything.
Can someone help me please? Thanks.
