hey Rene,

May i know what is your Joomla version from your site?

To be honestly, I didn't change anything from your site, but that was known issue when you using older version of Easydiscuss 3.x, but this issue already fix in Easydiscuss 4.

Actually that error just a warning message, it will not cause any issue from your site.

But for now, Can you try apply this css from your backend template css file? It should hide that warning message from backend Easydiscuss page.

.com_easydiscuss #system-message-container .alert {

     display: none !important;

}

Note : If you using Isis Joomla default backend template, you can apply above css code into this template css file -> JoomlaFolder/administrator/templates/isis/css/template.css, after you applied the css code, you have to clear your Joomla cache and browser cache before you access your backend site.

Yes i use release 3.x

You told me that 4.x isn't compatible with 3.x Themes.. I use many css-hacks..

I believe it would be fine if use css hack, because this css hack will not causing another issue.

You told me that 4.x isn't compatible with 3.x Themes.. I use many css-hacks..

Hm, I am sorry for that because I can't remember when I told you that Perhaps you can share with me which thread I told you before?

By the way, it would be best if you can setup a test site and try to upgrade it from 3.x to Easydiscuss 4 and see is it everything look fine. Because we have improved some of the styling in the latest themes in Easydiscuss 4.
