This guide covers most, if not all, changes required to un-tie your site from Osclass Market
If you know some changes that we forgot, post it on our forums or contact us via the links above.
As a test if this mods were successful, we put "error_log('cURL:'.$url);" in "osc_file_get_contents" function.
We visited admin homepage, plugins, themes and language pages, settings page, we checked for updates, we ran cron, etc.
There wasn't a single cURL log that says that a request has been made to Osclass.
