I am using WordPress version 5.4.2 and my domain is hosted by Hostinger. For the last few days, my website kept crashing and so I contact the support where I was advised to do a fresh install of the latest WordPress. As per their advice, I did upgrade WordPress to the 5.4.2 version. After upgrading the website worked but then 5 minutes later, crashed again.
Looking at the error that keeps coming up, it appeared that the file wp-load.php keeps going from 3kb to 0kb at its own will and this is then crashing my website?
Any suggestions on what needs to be done to solve this issue?
