TOPIC: Show "read on" off killed JoomlaComment

Hello,

I got a little problem with the "show 'Read on'" option, since when I tried to desactivate it, JoomlaComment disappeared from all the articles on my website where it used to be available. Worst, when I put it back to "on", it doesn't reappear.
I've been doing so first on Joomla 1.5.4 with JoomlaComment 3.26, just after an upgrade of both. I tried to come back to the former versions I have been using (Joomla 1.5.2 / JoomlaComment 3.20), but the same try had the same effect. I uninstalled JoomlaComment 3.20 to replace it with JoomlaComment 3.26, but it didn't make the comments reappear (on the webpages - the database is fine).

Below is the only code that appear where the comment module used to be:

<!-- START of joscomment --><div id='comment'><div id='Comments'>
<script type='text/javascript'> var JOSC_postCSS=2;</script></div><div id="poweredby" align="center" class="small">Powered by <a target="_blank" href=" compojoom.com/ ">!JoomlaComment 3.26</a></div><h4 style="display:none;">3.26 Copyright (C) 2008 Compojoom.com / Copyright (C) 2007 Alain Georgette / Copyright (C) 2006 Frantisek Hliva. All rights reserved."</h4></div>
<script type='text/javascript'>
var JOSC_ajaxEnabled=1;if (!JOSC_http) JOSC_ajaxEnabled=false;var JOSC_sortDownward='0';var JOSC_captchaEnabled=true;var JOSC_template=' www.website.com/media/myjosctemplates/mySSlide-emotop';var JOSC_liveSite=' www.website.com/components/com_comment/joscomment';var JOSC_ConfigLiveSite='http://www.website.com';var JOSC_linkToContent=' www.website.com/index.php/contact.html';var JOSC_autopublish='0';
</script>
<!-- END of joscomment -->

Any idea of the reason, or at least of a way to bring JoomlaComment back on my website?

Thanks in advance for any suggestion!

Is the bot published?

Yes, it is. I've just tried to unpublish/republish it, nothing changed.
By the way, when it's unpublished, I don't even have the code copy-pasted in my first post (which is somehow logical ).

Can I see your web site. Super admin access will be also very good

I think I have found the reason: it was visibly related to the fact I'm using a customized template. When I disabled it to come back to a standard one, the comments reappeared.
What remains strange is that I had only edited the colors from an existing theme. But I recreated the .css file, and it seems to be fine again. Maybe a character encoding issue?

Thanks anyways for your quick offer of help!
