Hi,

I'm having a strange behavior on DNN 9.04.01.

I copy and paste my HTML code (very simple code) but after saving, all css classes are removed.

For example:

ul class="bxslider"....

becomes 

ul ....

without my class.

So it looses every behavior assigned to the class (in this case images slider).

What I've to do?

Thanks

That's the default behaviour of the CKEditor (the component used as the editor). It's for security reasons. Read more about it here: https://dnncommunity.org/...-is-cleaning-my-HTML

BTW, I would advise you to upgrade DNN to the latest version (also for security reasons). Also as have a look at the structured content modules for DNN like Open Content or 2SXC. Managing a slider inside the Editor is very cumbersome compared to those modules

 

 

Thank you,

by inserting the string value *(*);*{*} in extraAllowedContent I can save my classes.

Have a nice day!

For me, this does not work anymore. It only works for me if you use *(*)*{*} without the semi-colon inbetween.

Also note to anyone that might reference this thread, clear cache via server persona bar admin settings if you don't see it working after save.

Oh wow, this saves me from loosing hair because of head scratching. I immediately noticed this behavior in my HTML module while editing a simple bootstrap column and adding a class on it. So, I started crawling for answers and viola. Thanks

Indeed... Any HTML that is complex in nature or has any risk of people (and web-based editing tools) breaking the HTML should instead use a structured content module instead of the HTML module.  As Timo has suggested, the two most popular options currently are OpenContent and 2sxc.

How does this "fix" the issue for pages and modules already added?

If you already edited the content on some pages and part of the content has been stripped and this is in the HTML module, you can use the versioning of the module. For any other module, I think the only solution is your backup.
