On one of my sites it all works fine.
But on another site not. The disqus comments do show on my "desktop" blog pages but not on the corresponding "mobile" blog posts. For the mobile pages I use a separate m.example.com domain.
For the mobile domain I use the nokia_mobile theme.
For this site, on the mobile pages, the disqus js code that should be there at the end of the page is completely missing. I de-installed the disqus module and re-installed it again but, nothing helps to get the code there.

Thus the weird thing is that on another site, it all works well. On that site the disqus comments show both on the "desktop" posts as on the corresponding "mobile domain" pages (the js code is there on these pages).

The difference between the two sites is that the site that works uses the older Disqus module 6.x-1.6 while the site that does not show the comments on the mobile pages uses the latest module 6.x-1.9. Both sites use the same mobile theme. The site where it does not work uses quite a number of different (I thought unreletad) modules that are not used in the other site where it all works fine.

Key issue is that this js code does not show on the mobile pages of this one site (the Disqus comments block is there in the code). Anybody any suggestions where to start looking for a solution?

Here is an example of the desktop and mobile URL for the site that does not show the comments on the mobile pages;
http://www.stocktrendinvesting.com/blog/investing-your-savings-sure-and-...
http://m.stocktrendinvesting.com/blog/investing-your-savings-sure-and-si...

And here are the URLs for the site where all is working well:
http://www.drupalinternetbusiness.com/content/ultimate-drupal-6-mobile-s...
http://m.drupalinternetbusiness.com/content/ultimate-drupal-6-mobile-sit...

Your suggestions are welcome.
