Because my hosting provider told that the apache was shutted down not through ssh, and the only way to shut it down was through webmin. Yea they were secure, webmin only accepted connections from my hosting ip so its strange but now, only from my dedicated I can connect to vps and I hope nothing like this happens again
I knew most of you are using lautaro's web files and I want you to check your webengine files for code similar to below. The code below can enable anyone to submit a direct sql query in your database. I found this code in webengine.php so start looking in this file. If you found any code similar to that then simply remove it.
