I'm relatively new to wordpress. Meaning, as long as it's working properly I can navigate and operate my site. But if it's not (like now), I'm lost. My brother originally setup my avisio website. I'm currently using the same theme, but changing it into a new website. I had to upgrade my PhP right off the bat because mine was outdated. However, when I did, lots of stuff began behaving strangely. For one, the slider doesn't move, nor does it display images that are uploaded to it. Also...
-I can't get a logo to appear at the top-right corner of the mainpage anymore.
-My video links actually send you to youtube rather than opening the link over my website page like it used to.
-My toggles don't toggle anymore either. They're just unresponsive when clicked on.
