In fact I found the solution.

4. Check Shortcode and Calendar Settings

• In your page/post shortcode (e.g., [add_eventon]), ensure no conflicting options like ux_val=0 (which forces popups). Try adding ux_val=2 to prioritize ”learn more” links, which can fallback to external URLs if no internal link exists.
• Example shortcode: [add_eventon ux_val=”2” event_type=”your-event-type”].
• In EventON > Settings > General, confirm Event card interaction isn’t overriding to popups.

Correct was indeed 4 not 2. But this was the solution.

For others who have same problem:

Yes, that’s spot on—the shortcode and calendar settings are often the culprit for external links misbehaving in EventON, especially if `ux_val` is set to a value that defaults to popups (like 0 or 3). Here’s a deeper dive to nail this down, based on the latest EventON docs and common fixes:

### Key Shortcode Tweaks for External Links

– **Avoid Popup-Forcing Values**: Double-check your `[add_eventon]` shortcode for `ux_val=0` (do nothing on click) or `ux_val=3` (lightbox popup), as these override per-event external links. Instead, use:

  – `ux_val=”2”` for ”Learn More” mode: This prioritizes any ”Learn More” URL set in the event editor. If none exists, it falls back to the external link (or the default event page).

  – `ux_val=”4”` for direct ”External Link” mode: This forces clicks to open the external URL immediately, bypassing popups entirely.

– **Full Example Shortcode**:

  “`

  [add_eventon ux_val=”4” event_type=”your-event-type” cal_id=”1”]

  “`

  – Add `cal_id` if you have multiple calendars on the page to avoid JS conflicts.

  – Pro Tip: If copying from docs or forums, retype quotes manually—curly quotes (“ ”) from rich text can break shortcodes.

– **For Single Events**: Use `[add_single_eventon id=”123” ux_val=”4” ext_url=”https://example.com/tickets”]` to hardcode an external URL per event.

### Calendar-Wide Settings Check

– Head to **EventON > Settings > General > Event Card**.

  – Look for **Event Card Interaction** (or similar UX options). Set it to ”External Link” or ”Learn More” globally—this acts as a fallback if shortcodes don’t override it.

  – Ensure **Disable Event Links in Description** isn’t checked if your external URL is embedded there.

– In **EventON > Settings > Appearance**, confirm no custom CSS is blocking link styles (e.g., `pointer-events: none` on event cards).

### Quick Test & Debug

– Update to the latest EventON (v4.5+ as of late 2025) for UX fixes, including shortcode generator improvements.

– Flush permalinks (Settings > Permalinks > Save) after changes.

– Browser console check: Right-click > Inspect > Console. Click an event—if you see JS errors (e.g., related to `ux_val`), it’s likely a conflict; deactivate plugins one-by-one.

If this doesn’t click through after testing, drop your exact shortcode and EventON version for more specifics!
