🔥 Critical Bug Fixes

Version 0.2.2 resolves critical issues preventing email delivery in v0.2.0 and v0.2.1.

Priority: CRITICAL - All users should upgrade immediately.

What's Fixed

1. Double-Encryption Bug ✅

Problem: API keys became corrupted when settings were saved multiple times, causing authentication failures.

Solution:

  • ✅ Added automatic detection to prevent re-encryption
  • ✅ Auto-repair of existing corrupted keys on plugin load
  • ✅ One-time migration runs transparently
  • ✅ No user action required

2. API V2 Compatibility ✅

Problem: Plugin was sending unsupported fields causing 500 Internal Server Errors.

Solution:

  • ✅ Removed SubmittedContentType, IsHtmlContent, ReplyToEmail fields
  • ✅ Made SenderName optional (only sent when not empty)
  • ✅ Added default values for empty subject/message fields
  • ✅ Full compliance with EnjinMel V2 API spec

📥 Installation

WordPress Admin (Recommended)

  1. Download enjinmel-smtp-0.2.2.zip below
  2. Go to Plugins → Add New → Upload Plugin
