Iintruder - My SMF-Homepage can no longer be accessed

[Gerd 66]

SMF 2.0.17
at the provider: MySQL version 5.6
at the provider: PHP version 7.3


The homepage of my forum is no longer displayed. There is no error message when called. This is the only malfunction that I have noticed so far.

With the following call I can call the corresponding boards normally:
https://www.example.org/index.php?board=2.0

Then I can log in as an administrator.
To my surprise, I noticed that a board was created with the following name:  Günstig einkaufen (Buy cheap)

For users logged in https://www.example.org works normally.

How can the Intruder prevent https://www.example.org from displaying the forum homepage?

there are many ways a hacker could have modified things if they got in...  Although there are currently no known security issues in 2.0.17, if they found a new one or they found a way in because the HOST was not secure, then they could have made edits to files or even the database.

we need more details.

like the actual URL of your site?

If you have access to them, in your HOSTING cpanel, check the server logs for the day this happened...    also check the file edit dates.
