Can you paste the html codes here, that you are trying to add?

Home = Customize this page = Custom text/html = (type anything) = Save Button (nothing).

There is no any html code.
Just the box of the Custom text/html. The Save Button does nothing.

I already deactivated the Site CK Editor and the Cool CK Editor. Then the Custom text/html works fine.

When doesn´t work the dialog box of the custom/text html is larger than the dialog box of the same when is working.

I search in the forum something about, the closest issues tells something about the Debug mode, but I don´t know where it is.

Thanks.

As far as Ow_Debug is concerned, a nice article is available here.

If you are facing compatibility issues then you need to contact the plugin developer directly.

Thanks. How can I know if there is or there is not a provider compatibility issue?

Disable all 3rd Party Plugins and see if your probelms still persists, If not, then you got compatibilty issues.

Enable 3rd party plugins one by one and see if problem comes back, and in this way you can check which plugin is making trouble...

Ulises, you will need to contact Site CK editor and Cool CK editor plugins developers to resolve your issue. 

Even though the plugin may be compatible with the current version of Oxwall software, there still can be some bugs which need to be fixed. 

The compatibility of the plugin with the software is shown on the plugin page, which version of the software plugin supports.
