I don't think you should necessarily create a new topic about the preview problem. It may be better to change the subject (in your original message) to reflect the current status. From the sounds of things, the preview problem (in your case) still exists.
I have looked into many cases over the years about why the message preview feature does not work. There are several possibilites and, in nearly all cases, these have involved conflicts between
Kunena and Javascript used by other [third-party] extensions.
One such extension that is known to cause problems is a thing called
JCH Optimize
; that's just one product that I know that doesn't work with
Kunena.
You need to remember that the message preview feature uses AJAX; AJAX, of course, uses Javascript (even though the script is executed on the server and not on the [browser] client). So, the most likely explanation as to why the message preview feature does not work in your case is Javascript-related in some way.
There may be other causes, too:
- One case, that had me totally mystified, involved a situation where certain words or characters would stop the preview feature from working! It was very hard to reproduce this scenario.
- In another case, the problem related to the use of Internet Explorer.
- In some other cases, there was a problem if the Kunena - Community Builder plugin was enabled.
If you search this forum for preview problems, you will probably find other interesting cases, too.
In any event, the most likely cause of your problem is a Joomla extension—a template, component, module or plugin—that loads its own Javascript library that conflicts with
Kunena. The trick is to isolate that extension, disable or uninstall it, and see if it's the cause. This could require a lot of time on your part (with or without the assistance of someone else).
One possible topic that may help you (even though the discussion took place a long time ago) is:
K 3.0.2 message preview not working
. I hope some of this helps.
