Registration or room pages show a 404:
Go to Settings, Permalinks in WordPress and click Save once. That rewrites the link rules and the webinar pages start resolving. The plugin also answers a query string version of every link for sites running plain permalinks. For a permanent fix, publish the registration page as a WordPress page. See Publishing Your Registration Page As A WordPress Page.
Nobody received their confirmation email:
Open Diagnostics and read the email lines. Then open the Email screen, save your settings and press Send a test email. Confirm your sending method is a real provider rather than plain WordPress mail, that the From address is at your own domain, and that your provider has verified that domain. Check the spam folder too.
Reminder emails are late or missing:
Check the WP-Cron line in Diagnostics. On a quiet site WordPress cron only runs when somebody visits, so a real server cron scheduled by your host is far more reliable. Also confirm the reminder is ticked on the Emails tab, because reminders start switched off, and that your from address uses your own domain.
Changes to my registration page are not showing:
Edits on the Registration tab save to a draft. Press Publish to the live page and visitors will see them.
Somebody cannot register again:
If the webinar is set to One registration at a time on the Schedule tab, a person with an active booking is shown that booking instead of getting a second seat, until the number of days you set has passed. Cancelling their registration frees them straight away.
My cloned voice is not in the narrator list:
Open the Results AI Voice Engine app on the same computer, enable its keep running and network access options, then reload the webinar editor. Keep the app open while you generate. German narration needs a cloned voice, because there is no built in German voice.
Narration failed on some slides:
The status line reports how many slides failed. Click Generate Voiceover again and it fills in only the missing ones. If nothing generates at all, try a current desktop Chrome, Edge or Brave, since narration runs in the browser.
Chat feels slow with a big audience:
Check the live chat folder line in Diagnostics. If the folder is not writable, ask your host to make the WordPress uploads folder writable so the fast static delivery is used.
My broadcast will not start:
Use Chrome, Edge or Firefox for a broadcast from this site, and allow the browser to use your camera, microphone or screen when it asks. Check that the uploads folder is writable in Diagnostics. If you chose Cloudflare Stream, confirm the connection with the Test connection button in Settings.
The live recording has not appeared as the replay:
With a Cloudflare broadcast, streaming providers need a few minutes to process a recording after you stop. Wait, then click Use my live recording as the replay in the Live panel. A broadcast from this site is saved as the replay when you stop.
An autoresponder is not receiving registrants:
Save your settings, then click Test connection for that provider. Confirm the list, audience, campaign or form ID matches the list you are watching. For AWeber (Legacy), register a real test seat, since its details cannot be verified by an API call. If the webinar is set to Choose which connections fire, make sure that connection is ticked for the webinar.
A tab will not save:
Each editor tab saves as you make changes, and has its own Save button. Make sure you clicked Save on that tab, and watch for the note beside it confirming the save.
Still stuck:
Run the Diagnostics tab first, since it checks PHP, the REST API, cron, the chat folder, email delivery, your license and streaming in one place. Then contact support at onlineimsupport.com with what it showed you.
