Maximum image size allows you to limit size of images uploaded to listings. There is hard limit coming from your PHP setting and is shown in message “Maximum size PHP configuration allows: 1234 KB”.

Following function is used to resolve limit. It’s minimum of 3 PHP settings.

$max_upload = $this->_sizeToKB(ini_get('upload_max_filesize'));
$max_post = $this->_sizeToKB(ini_get('post_max_size'));
$memory_limit = $this->_sizeToKB(ini_get('memory_limit'));

$upload_mb = min($max_upload, $max_post, $memory_limit);

Latest searches

This page will allow you to decide if you want to store the latest queries of your users and for how long. It may be useful to know what queries users make in your website. You could have an idea of what your users are looking for or show them on the site as “hot topics”.

  • By default, this option is unchecked.

Advanced Settings

Allow you to choose if you want to enable subdomains on your Osclass website. If you enable them, you can choose by which subdomain type they will be based on: user, category, country, region or city.

  • Remember that if you enable subdomains, you are required to provide your host name. Add it without “www”.
