FrontEnd - Problem to modify an article (save or cancel)

Hello together ! I'm a newcomer in this forum and a french guy, so I'm going to try to explain my problem as good as I can be :roll:

I had no problems with the installation of FlexiContent 1.5.3c on Joomla 1.5.21. No error messages occurred ... But when I edit an article from the FrontEnd, then I modify the text and I'm not able to save or cancel !
When I click on the save button, my modification disappear and when I click on the cancel button, my modification disappear too but I'm still in editing mode.

Is that something I didn't understand ? Do I need FlexiAccess to make it works ?

Thank you very much. Julis.

hello it's a javascript conflic
try to desactived mootools plugn for compatibility
clean cache and cache expired
try again
regards

Thanks a lot for your fast reply.

I disabled the mootools plugin adding this script within the index.php of the template (rhuk_milkyway).

script:

<?php
$user =& JFactory::getUser();
if ($user->get('guest') == 1) {
$headerstuff = $this->getHeadData();
$headerstuff = array();
$this->setHeadData($headerstuff); }
?>

But without results. The only difference was that the JCE Editor was disabled too. (Before posting the first question, I already tryed to disabled editors).

I also deleted the "if ($user->get('guest') == 1) {" to make it works for every users.

What do you think it otherwise could be ?

Oh yes, I forgot, I also cleaned the cache and expired cache ...
