I was on my site having a PM conversation and whatnot when suddenly my site's home page went blank and I got this when attempting to access admin:

Code:
[HEADING=1]Server Error[/HEADING]
 
fopen(/var/www/vhosts/xx.net/httpdocs/internal_data/install-lock.php): failed to open stream: No such file or directory

I have PHP 7.3.17 on Ubunto 16.04 and Apache. I don't recall ever getting this error before and I was just using the site as usual. The install-lock.php file exists and I even tried giving it full permissions, but nothing. Help!!
