[imp] Emoticons (smilies, smiley) giving cert error

[cjdl01]

Hi Again,

I'm having a strange error when my users attempt to use the "smilies"  
in their emails.  The red pop-up comes up saying that it is unable to  
communicate with the server, but the real detail comes when they click  
on any horde component after this error (for example, click on  
"calendar").  Then I get a big red pop-up that says this:

Problem with  
https://www.myhordedom.com/horde/js/ckeditor/plugins/smiley/images/regular_smile.gif: fopen(): SSL operation failed with code 1. OpenSSL Error messages: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed. fopen(): Failed to enable crypto. fopen(https://www.myhordedom.com/horde/js/ckeditor/plugins/smiley/images/regular_smile.gif): failed to open stream: operation  
failed

I am current on all things horde (as far as I know).  The smiley files  
are where they should be on the server:  
~/horde/js/ckeditor/plugins/smiley/images and the perms are  
sufficiently lax. I can put  
https://www.myhordedom.com/horde/js/ckeditor/plugins/smiley/images/regular_smile.gif in my web browser and it renders the smiley  
appropriately.

Now, I know that this is saying it is an https issue, but I do NOT use  
self-signed certs.  My certs work just fine in all other regards, and  
do not expire until christmas eve of this year.  So there must be  
something else going on (or it is a bug).

What could be going on here?

Thank you!
