Hello,

After setup in Plesk all pages except the home page redirects to 404. 

Any help please?

You need to check the htaccess you have in place, and ensure thet rewrites are switched on 

There was no .htaccess file. I created one and put this inside.

 

<IfModule mod_rewrite.c>
Options -MultiViews
RewriteEngine On
RewriteBase /forum/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule \.(jpeg|jpg|gif|png)$ /forum/public/404.php [NC,L]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

That seems to solve the problem. But I don't know if it is ok.

You need to download one from the System>Search Engine Optimisation section of your admin CP. According to where your URL is on file, that htaccess would not be correct.

Perfect, I did it. Thanks for the help.

No problem at all. Glad you have what you need there
