Hello Klas, thanks for take a look..
this msut be something on your server or settings - what kind of user
do you use for this? What is TextFiltering setting in the global
configuration for this group? Do you use different profile for this goup
in JCE and what are security related settings like prohibited elements?
First guess for me is my something server setting, but this is not happen when I submit article with default joomla article. Joomla Article = No problem from front end and with same account.
I use group named "front-end access" just only can login from from end. but after your answer I change that account to superadmin, but the result is still same.
I change text filtering setting in global configuration to "No Filter" but still same problem occured.
I dont use JCE, just standart TinyMCE on joomla 3.3.6, recently even I use NoEditor to directly write code such as :
<p><img src="/images/article-image/my-image.jpg" alt="" /></p>
<br>
but after hit button save, the result is still become something like this :
<p><img src=\"images/article-image/my-image.jpg\" alt=\"\" /></p><br>
and when I take a look second time, and save again, that code become like this (the \ sign multiply to 3)
<p><img src=\\\"images/article-image/my-image.jpg\\\" alt=\\\"\\\" /></p>
Thankyou for help for everyone..
regards
