I have been developing a Wordpress site locally using MAMP, and I have run into an issue twice now where when I leave at night and come back, I can't access the admin page. I have debugging on, and there aren't any fatal errors. I can access the front-end of the site just fine, but I can't log into the admin page. All I get is a white screen like:
Here is the front end:
As you can see the front end is working well, but I can't get into the admin section. I've tried to re-login and it just doesn't work.
What could be causing this? The last time this happened, I had to reinstall the entire site. I really don't want to do this every day. I know that everything was working when I left, and I haven't made any changes today.
It also looks like this happens with some frequency, as there is another user with a similar issue: Cannot access admin panel
I tried all the suggestions on the linked question, but that didn't work.
