Ok so this happened to me the other day and I was able to resolve it by reinstalling WordPress, my WordPress theme and all of its plugins (took forever)
It has now happened again so I need to get to the root of the issue.
I have a website running on my localhost (using MAMP)
When I visit localhost:8888/ I am able to access my entire file directory.
All other sites on my localhost are loading without issue, except for the site I need to access. I am getting a 500 error in the browser.
When I enable WP Debug it doesn't change from the 500 error in the browser.
I have not modified this site in any way to cause this issue, it literally just randomly bricks itself. The same thing happened before to the exact same site.
I have gone through a ton of guides and am completely lost at what is causing the issue.
Would really appreciate some help troubleshooting.
This is my latest error log from apache.
