Vimeo Player iFrame no longer displays in Dreamweaver for all projects. Video plays fine on website

[Jim Norman]

This morning I opened Dreamweaver to update a web page which contains an iFrame using code from Vimeo.  None of my project index files now display the iFrame and associated video.  Nothing has changed and when you view the websites, the videos are present.  Dreamweaver is up to date and displayed the iframes and videos a week ago.   Again, the actual websites display the videos okay.  Any suggestions?  I even pasted in the latest Vimeo embed code, but it made no difference.  Runing Windows 10 which is up to date.

Switch from Design to Live view (Ctrl +Shift + F11).  Live view behaves more or less like an actual browser, although it isn't one.

If video works on the site as it should, you have no problem. If it stops working on the site, then you have a problem.  Validate code & fix reported errors.

Nancy,

Thank you for the reply.  Unfortunately, none of the videos display in Live view either.   I have two computers I use for development and video editing.  The one that I am having the problem with is running Windows 10.  The second computer runs Windows 11.  I just installed Dreamweaver on the Windows 11 computer and it works as expected.     Unfortunately the Windows 10 computer hardware doesn't support Windows 11, so I cannot upgrade the OS on it.  Any other suggestions?  Any other suggestions?

Thanks.

Might be something on Vimeo's end or a security setting in Windows that's blocking external content.

Test with this YouTube video and see if it displays.  Save file and hit Refresh (F5).

The other thing to try is Restoring Preferences. That fixes most problems in Dreamweaver.

Nancy,

I tried the YouTube code and it works okay. I also reset Preferences, but
no change. As mentioned, the same project files display the Vimeo videos
on the Windows 11 computer.

If I highlight the video embed code, the iframe appears on the screen, but
there is no Vimeo player/video inside.

Nancy,

I thought that I was using the latest version of Dreamweaver on my Windows
10 computer. I was using Version 21.0. When I installed Dreamweaver on my
Windows 11 computer which did not have the problem, I noticed that the
version that installed was 21.3. I went back to my Windows 10 computer and
uninstalled Version 21.0 and installed Version 21.3 and the problem is not
there. I was pretty sure that I had checked Creative Cloud and thought
that an update was not needed, but I must have been mistaken. The odd
thing is that I am assuming that I was using Version 21.0 for years without
this problem. Perhaps it became incompatible with some other software
running on the computer.

Thank you again for your assistance.

Best wishes.

I haven't noticed any discernible differences between ver 21 and 21.3 on Win10.  But maybe the new installation cleared out whatever the problem was.  Glad you got it sorted. 🙂
