Please show me where you upload .mov file?
If from here: https://gyazo.com/13a6abbbff7b5e79bfbaa757989ded8c => just support 4 type files in image.
Under a Property > Property Information > File Attachments > Add File, opens the WordPress Media Library to upload any file format. Does not look like your screen shot, just a single button.
I suppose this image src icon is dynamic and looks at the extension of the uploaded file attachment to grab the related image in your plugin folder, but .mov is missing. You have 21 other file formats/extensions in this images/attachment folder. I would suggest adding an attach-mov.png file too as it is a common format and the Media Library or your plugin does not restrict uploading it as suggested. Or add a check to verify the png image exists before showing it on the frontend so it at least doesn’t show a broken image.
I’ve created my own attach-mov.png file and manually uploaded it to this folder to fix for now. Thanks.
Thanks for let me know about it. I will transfer to our developer team to add it. Thanks once and hope you like our plugin.
Fixed by update new version. Thanks
