+### `Timeout` errors
 Some users have reported a successful installation, but get a blank page due to a `timeout` on a PHP script that prepares the forum assests (`Minify.php`, notably).
 In `/etc/php/7.0/fpm/conf.d/20-{APPID}.ini`, you can increase the `max_execution_time` and `max_input_time` limits (both values are in seconds if nothing is specified).
 Reload PHP-FPM with `sudo service php7.0-fpm reload`.
 
-#### Upload limit
+### Upload limit
 If you are facing an error while uploading large files into the forum, PHP may be limiting file upload.
 In `/etc/php/7.0/fpm/conf.d/20-{APPID}.ini`, you can uncomment (remove `;` at the beginning of the line) and increase the values of `upload_max_filesize` and `post_max_size` (both values are in bytes).
