I wrote the text first in the previous post, then added the embedded article which appears at the top. Then added the link at the end where it appears. In a classic forum, article links appear at the top, but apparently not in Zeta.

thanks for the details  ...

Copy the raw HTML code before you hit the post button and compare it to the raw HTML code after you've posted it by editing the message and then going into <Source> mode.

You should see several differences. 

I would presume it's something in the original HTML that the Delphi processor either rejects or converts to something else that might be the cause.

Exercise is a key part of staying healthy, but figuring out how to get more active can be tough. If you're not used to physical activity, start slow. Go for 10 to 15 minute walks, and work your way up to briskly walking or jogging for 30...

Comparing your original to my posted copy of your original, it looks like Delphi editor has broken up and re-ordered several [<div class=] tags which seems to be the problem.

FWIW

How do we bypass the div tags?

The Delphi editor modifies them, so you'll have to remove them or replace them with other tags that the editor won't modify.

Edited to add: Or get Delphi to modify their editor and allow those tags "as is"... unmodified!

FWIW

We have to live with the editor we have now.

Then you will have to remove the offending tags.
