Hello @etneebrand

Thank you. The issue arises due to the caching of our plugin data on your website. Please do the following:

1. WordPress Admin → Settings → Anti-Spam by CleanTalk → Advanced settings:
   — set the “Set cookies” option to “Auto”;
   — click Save Changes.
2. We detected that you are using the WP Fastest Cache and Autoptimize plugins. Please make sure the cache TTL is set to 24 hours or less — this is very important.
3. Purge all caches
   — Cache plugin cache
   — Website/server cache
   — CDN cache (if any)

If you notice any new false positives again, please let us know.

Hello @sabineboogaard1985

Thank you for your request! We’ve reviewed your logs and can confirm that we do see allowed requests, even though there are corresponding entries in your Personal Lists. This behavior is not expected.

We’re investigating this issue internally and will get back to you with feedback and next steps within 1–5 business days.

Thank you for your patience. If you notice any changes in the meantime, please let us know.

Hello @hirejordansmith

Thank you for the clarification and for the screenshot. We’ll review the details and get back to you with an update within 1–3 business days.

Hello @maddogprod

We’ve just rechecked the Email Encoder on our side in multiple browsers (including Chrome and Firefox), and everything is working correctly at the moment.

If you notice the issue again, please let us know and we’ll take another look right away.

Hello @wphelpstuff

Both errors indicate that the Security Firewall and Malware Scanner received unexpected or corrupted data during an update.

Please try the following steps:

1. Clear any server-side cache (LiteSpeed / Cloudflare / WP Rocket / etc.)
2. Go to WordPress Admin → Settings → Security by CleanTalk → Synchronize with cloud

If the error returns, please open a ticket in our support system so we can investigate:

Hello @golfball-uhu

The issue occurs because some of the CleanTalk Anti-Spam data on your website is being cached. Please follow these steps:

1. In WordPress Admin → Settings → Anti-Spam by CleanTalk → Advanced settings:
   — Set “Set cookies” to Auto
   — Set “Use Anti-Spam by CleanTalk JavaScript library” to On
   — Click Save Changes
2. Please configure WP Rocket according to our recommendations:
   https://cleantalk.org/help/cleantalk-and-wp-rocket
3. Make sure the cache lifespan in WP Rocket is 24 hours or less — this is very important for correct Anti-Spam behavior.
   WP Rocket documentation:
   https://docs.wp-rocket.me/article/78-how-often-is-the-cache-updated
4. Clear all caches:
   — WP Rocket cache
   — Website/server cache
   — CDN cache (if used)

After applying these steps, please monitor the Anti-Spam logs here: https://cleantalk.org/my/show_requests.

If any new false positives appear, just let us know — we’re here to help.

Hello @tomscottjsh

Thank you very much for your detailed report — this is extremely helpful.

Could you please tell us:

• How often you see these 5–6 second blocking intervals (e.g., once per hour, once per day, etc.)?
• Which tool or method you’re using to collect the slow logs? This will help us reproduce the same scenario.

From your description, the slowdown happens during the SpamFireWall update process inside the Anti-Spam plugin. To confirm this, please open the plugin settings, disable SpamFireWall option, and save the changes — you can keep the main Anti-Spam protection active. This way, your site will remain protected while we verify that the issue is caused by the SpamFireWall update.

Once we have your feedback, we’ll prepare a patched build or an alternative cron configuration to prevent these updates from affecting live traffic.
