03/15/26 — 03/16/26 — Post-Submission Bug Fixes & New Features

03/15/26 — “Publishing failed” error with WordPress 6.9.4

• Root cause: transition_post_status hook was making synchronous HTTP calls to the Inkwell API inside the Gutenberg REST API request, blocking the response and triggering a publish failure
• Fix: detect REST_REQUEST and defer crosspost execution using wp_schedule_single_event + spawn_cron()
• Follow-up: cron never fired on host due to blocked loopback HTTP requests — replaced with shutdown action hook
• ignore_user_abort(true) added to keep DB connections alive after response is sent
• fastcgi_finish_request() called when available so PHP-FPM flushes the response to the browser before the crosspost runs
• Wrapped shutdown execution in try/catch (\Throwable) to surface silent fatal errors
• Fixed add_transient() unavailable in shutdown context after fastcgi_finish_request() — replaced transient lock with direct get_post_meta() check and force=true call in shutdown path
• Retained cron hook registration for any events already queued from previous version

03/15/26 — Debug Log page

• New admin page at Settings → Crosspost to Inkwell → 🪲 Debug Log
• Enable/disable toggle — off by default to avoid storing sensitive data unnecessarily
• Dark terminal-style log viewer, color-coded: green for success, red for errors, blue for outgoing requests, orange for API responses
• Refresh button (live AJAX reload) and Clear Log button with confirmation prompt
• Log stored in wp_options under inkwell_debug_log, capped at 200 entries
• Debug Log link added to settings page header and plugin action links row
• 26 log points added throughout the crosspost flow:
  • Cron/shutdown deferral and execution
  • Crosspost start (post ID, force flag, post status)
  • Transient lock and already-posted guard hits
  • Every outgoing API request (method, URL, payload keys)
  • Every API response (HTTP status code + first 600 chars of body)
  • Image upload — file read, encode, upload, result
  • Crosspost success with entry URL
  • All error and skip paths

03/15/26 — Verify Key: reads live field value

• inkwell_ajax_verify_key was reading the API key only from saved wp_options, so clicking Verify Key before saving always returned “No API key entered”
• Fix: JS now reads the current value of #inkwell_api_key and passes it in the AJAX request; PHP handler uses the submitted key if present, falls back to saved option

03/15/26 — API key field: show/hide eye toggle

• Added 👁 / 🔒 toggle button inline with the API key <input type="password"> field
• Button switches field between password and text type on click
• aria-label updates on toggle for screen reader accessibility
• Typing in the key field clears the connected account status display so re-verification is obvious

03/16/26 — Persistent connected account display

• After a successful Verify Key, the connected account name and handle are now saved to wp_options and displayed persistently on page load — no longer disappears on refresh
• connected_display_name and connected_username added to plugin options defaults and sanitize callback
• inkwell_ajax_verify_key refactored to make a single /api/me call (previously called it twice — once in inkwell_verify_credentials() and once again to extract data), saving account info and building the response message from the same result
• On verify failure, saved account info is cleared so stale data from a previous key is never shown
• Sanitize callback updated to pass through connected_display_name and connected_username from $input when present — previously always read from $existing (old DB value), silently overwriting the newly saved name on every update_option call
• wp_kses() used instead of sanitize_text_field() for display name to preserve emoji and Unicode characters (e.g. ΞVΞ🦋)
• API key change (via settings save) clears connected account info so stale name from previous key is never displayed
