SSL-check This tool will crawl an HTTPS-website (entire website, recursively, following internal links) and search for non-secure images, scripts and css-files that will trigger a warning message in browsers. The number of pages crawled is limited to 200 per website. The results are cached for 10 minutes.
@Jimmy As you are using IPB i want to ask if you know any way to make old topics/posts images using https but not manually as i know the IPB has an option to do that automated but for topics/posts that are created after enabling the related setting from admin panel.... ?
