Signature Guard Plugin for MyBB

MYBB PLUGIN free
Not rated yet Be the first

Over-limit signatures hidden on display and flagged to staff once — the stored copy is untouched.

Signatures that break your link, image or length limits are hidden when displayed and flagged to staff once.

• Nothing is destroyed: the stored signature is left exactly as the member saved it.
• Staff get one notification, not a flood, and can then ask the member to fix it.
• Limits are set in the plugin settings.

rebuilt as a versioned release from the source deployed on Data-Forums — the 1.x archive was not recoverable, so this is the honest 2.0 line rather than a lost original.

What's included

  • Signatures over your link, image or length limits are hidden from display and flagged to staff once.
  • The stored signature is never edited — the member can fix it, and the original is intact.
  • Flags are written to one table (df_sigflags) so staff see each member once, not on every page view.
  • Limits live in one settings group, so they are changed in the ACP like any MyBB setting.

Install it

1. Upload inc/plugins/df_sigguard.php to inc/plugins/.
2. Admin CP -> Configuration -> Plugins -> Install & Activate.
3. Set the link, image and length limits in the plugin settings.
4. Nothing is deleted from the database — the guard only changes what is displayed.

Questions people ask

Does it create database tables?

Yes — df_sigflags. Uninstalling drops them, so nothing is left behind.

Does it edit templates or core files?

No. It runs from hooks, so no core file is modified.

How do I check the file I downloaded?

Every release page prints a SHA-256 checksum. Hash the archive locally and compare — if the two differ, the download is damaged, not the release.

How are updates delivered?

Each version is its own release on this page with a changelog, and the older archive stays available. Install the new one over the old one; your settings and data stay where they are.
