If you’re running a WordPress multisite site and using the W3 Total Cache plugin, you may have noticed that non-super admin users (like subsite admins) can access the plugin's settings and see all it's dashboard elements, such as help tabs and meta boxes. This can be problematic in multisite environments where you want to limit access to critical configuration options while keeping the interface clean for subsite admins.

While working with WordPress and social media, I noticed an issue when sharing images on Facebook. Specifically, images with Greek characters in their filenames wouldn’t show up as og:image thumbnails, even though they were properly uploaded. To address this, I developed a simple WordPress plugin LS Sanitize Greek Filename, that automatically sanitizes Greek filenames. It converts Greek characters into their Latin equivalents, making the filenames compatible with platforms like Facebook, ensuring that images appear correctly when shared.
