If you're reading this, chances are you're using our Video Thumbnails plugin for WordPress and keep getting the message "No video thumbnail for this post." This can be frustrating, but walking through the steps below can help you fix the issue or at least narrow down the cause so we can help.
- Make sure you have saved any changes to your post.
- If you are using a a plugin or theme that stores videos in a special meta box other than the main post content editor, be sure you've entered the correct custom field on the settings page. If you don't know the name of the field your video is being saved in, you can try the "Automatically Detect" button in the settings or contact the developer of your video theme/plugin.
- Copy and paste your embed code into the "Test Markup for Video" section of the Video Thumbnails Debugging page. If this doesn't find the thumbnail, you'll want to be sure to include the embed code you scanned when you request support. If it does find a thumbnail, please double check that you have the Custom Field set correctly in the settings page if you are using a a plugin or theme that stores videos in a custom field.
- Go to the Video Thumbnails Debugging page and click "Download Test Image" to test your server's ability to save an image from a video source. You should see the image appear as well as be able to view it in the media library. Once you've verified that this is working, you can click the "Delete Test Images" button.
- Try videos from different sources will help narrow down the problem. If you've only tried with YouTube, try using a video from Vimeo to see if the problem is specific to one site. Be sure to include the sites you've tried when requesting support.
- Check the support threads to see if anyone is having the same issue.
- If you are still unable to resolve the problem, start a new thread with a good, descriptive title ("Error" or "No thumbnails" is a bad title) and be sure to include the results of your testing as well. Also be sure to include the name of your theme, any video plugins you're using, and any other details you can think of. The more testing and results you can provide, the better the chance of getting the issue resolved quickly!
