Hi javelindesign!

Yes, we’re very familiar with Memcached and how it works. However, the purpose of this plugin is to physically replace the files. What happens elsewhere on the website—such as caching mechanisms affecting your site or files—is beyond our control. That’s why we always recommend clearing all caches, including persistent object caching, after a replacement.

That said, I’ll discuss this with our team to see if there’s anything we can do. Since this is a free and open-source plugin, we’d also be happy to review a Pull Request with a proposed solution on our public GitHub repository: https://github.com/short-pixel-optimizer/enable-media-replace/

Thank you for your feedback!

Hi mikeecho,

Thank you for your feedback. However, we want to clarify that when you deactivate and delete reSmush.it, the plugin is completely removed from your site—this process is handled by WordPress itself. If you’re still seeing traces of it after deletion, it’s likely due to caching. We recommend clearing all caches (including any persistent object cache) to ensure you’re seeing the latest changes.

If you’d like to verify this behavior, you can test it on a fresh WordPress installation at TasteWP.com.

If you believe something isn’t working as expected, we’d be happy to assist—feel free to reach out to our support team.

Best regards,

Hey Jay,

This issue is likely caused by Cloudflare caching rather than an IP restriction. Enable Media Replace doesn’t rely on specific IPs, whitelisting, or blacklisting. The plugin simply replaces the physical image file and updates the database, so IPs are not a factor here.

Since your staging site works fine and only the live site (behind Cloudflare) has the issue, Cloudflare is probably still serving the cached version of the old image. To fix this, you’ll want to clear the cache for that specific file or adjust Cloudflare’s caching settings to prevent it from aggressively storing media files.

If the image appears updated in the Media Library but not on the front end, your site might also have additional caching layers, such as a page caching plugin or object caching (like Redis or Memcached), that need to be cleared.

You can also try temporarily disabling Cloudflare’s caching features to confirm whether that’s the root cause. If the issue resolves after that, you’ll know caching is the problem, and you can adjust settings accordingly.

Hope this helps! Let me know how it goes.

Cheers,

Hello swagatam1975,

Thank you for reaching out and sharing your concerns.

We want to assure you that our plugin, reSmush.it, is not infected with any malware or phishing threats. The last update to our plugin was made over two months ago, and it is actively used by over 100,000 websites without any reports of similar issues.

This is the first time we’ve heard of such a detection, and upon thoroughly analyzing the plugin, we found no evidence of any malicious code. It is highly likely that your antivirus software, Avast, has flagged the plugin as a false positive. Such incidents, while uncommon, can happen due to how antivirus tools interpret certain files or functionalities.

We recommend reaching out to Avast’s support team to report this issue, as they can investigate and confirm whether this is indeed a false positive.

We value your trust and are here to answer any further questions or concerns you might have.

Best regards,
