Latest Updates
View all releases- Automations — Modal Buttons Hidden Behind Backdrop Overlay:
- Fixed Duplicate, Delete, and Restore Defaults confirmation modals on the /automations page having their buttons unclickable due to the backdrop overlay rendering on top of the modal content. Same root cause as the global Modal.vue fix in v2.0.9 — the inline modals in Automations/Index.vue were missing relative z-[51] on the modal content container, causing the fixed inset-0 bg-gray-500 bg-opacity-75 backdrop to cover the buttons. Added relative z-[51] to all three modal content containers.
- Template Builder / Editor — Relative Image URLs in Emails (GitHub #6):
- Fixed uploaded images in the email editor ("Wgraj obraz" / "Click to upload image") being saved with relative paths (/storage/templates/images/...) instead of absolute URLs. Since email clients cannot resolve relative paths, images appeared broken in received emails. Root cause: TemplateBuilderController::uploadImage() returned a plain relative path without prepending APP_URL. Now uses config('app.url') to generate absolute URLs (e.g., https://yourdomain.com/storage/templates/images/xyz.png). Images uploaded via the Media Library were not affected.
- Dark Mode — Stats Page Month/Year Selector Invisible Text (GitHub #7):
- Fixed month and year <select> dropdowns on the Global Stats page (/settings/stats) having invisible text in Dark Mode. Root cause: the selects had no explicit dark:text-* class, so the text color defaulted to a dark value that was invisible against the dark background (dark:bg-slate-800). Added text-slate-900 dark:text-white to both selects.
- Modal Overlay — Content Hidden Behind Backdrop:
- Fixed all modal dialogs (Delete, Copy, and others) having their content hidden behind the semi-transparent backdrop overlay. Root cause: the modal content container in Modal.vue had default static positioning, causing the absolute inset-0 backdrop (bg-gray-500 opacity-75) to render on top of it. Added relative z-[51] to the modal content container to create a proper stacking context and ensure the modal body always renders above the backdrop.
- Mailing Lists — Grid View Action Buttons Unresponsive:
- Fixed all action buttons (Subscribers, Create Message, Edit, Clone, Delete) on mailing list cards being unclickable. Root cause: the list name <Link> contained a <span class="absolute inset-0"> overlay that covered the entire card (which has position: relative), intercepting all click events and redirecting to the edit page. Added relative z-10 to the action buttons container to elevate them above the overlay.
