Enable Guest Posting Safely with Joomla CAPTCHA

Guest posting is disabled by default in QCLF 1.1.27. When enabled, every guest Topic or permanent Message still requires a working Joomla CAPTCHA provider before the server accepts the submission.

QCLF recommends moderator approval and stores a guest display name plus private email address so moderation and abuse controls can identify the submission without creating a Joomla account.

Configure Joomla CAPTCHA First

  1. Configure and test the intended CAPTCHA provider in Joomla so Joomla reports a non-zero CAPTCHA plugin.
  2. Open Components → QC Live Forum → Settings and find Guest Posting.
  3. Set Allow Guest Posting to Enabled, then independently choose whether Guest Topics and Guest Messages/Replies are allowed.
  4. Keep Require Moderator Approval enabled unless there is a deliberate reason to publish immediately after server checks.
  5. Set the guest posting delay and maximum links, save, then test from a signed-out browser.

Server Enforcement Cannot Be Bypassed by Showing the Form

If no CAPTCHA provider is configured—or the configured provider cannot load—the guest form warns the visitor and the server refuses submission. CAPTCHA validation occurs for each guest Topic and each guest permanent reply, so merely removing/hiding the widget does not enable guest posting.

Current Defaults

  • Allow Guest Posting: Disabled.
  • Guest Topics: Allowed once guest posting is enabled.
  • Guest Messages / Replies: Allowed once guest posting is enabled.
  • Require Moderator Approval: Required.
  • Guest Posting Delay: 30 seconds.
  • Guest Maximum Links: 1, combined with the normal Category link limit by enforcing the tighter value.

Section and Category Overrides

Section/Category content-policy layers can override whether guest posting is enabled and whether approval is required. The global Guest Topics/Replies switches, guest delay, and guest maximum-links values remain global settings.
