Yeah It is a bit overwhelming but I was somewhat catching on to the things you just said! I am also not the greatest at explaining so forgive me! :)
Here is a link if you are curious: Personal Site Link
I’ll try to explain it as simply as I can. I have the code for the header portion of my site inside header.php file, and the footer inside the footer.php file.
In the WordPress menu bar on the left, once you click the pages tab, I created a page known as “content” and put all of my “main-content” code which is anything between the header and footer inside there. In the settings tab under reading, I have my site displaying a static front page which is linked to the “content” page I created. This is how everything is being displayed for my site right now.
The issues with both plugins is that the CF7 plugin only displays when I insert the shortcode inside that “content” page I created and the ACF plugin won’t. I need to stick it in an actual .php file. Once I did, it works although being displayed after all the “main-content” stuff rather than inside the work section where I want it to go :/.
What exactly is the Custom Posts Types UI?
