Well try to make the background color of the page let's say red. I guess that is in the D-template?Iàm not sure what you mean with flipback to it's original colors,can you make a screenshot from your settings
The css is modified to red. I can see that. But the page (inlineframe) stays white once displayed. You can see it goes to red but it becomes white again.
Just change only the background in D-template to red or whatever color you like but not white.
and see what happens when the page is loaded in the browser. It goes to your selected color and then immediately changes to white again. So am i changing the right color or what am i doing wrong?
About the other suggestion of the spam message. Sure i can modify this. But i have todo this every time i upload the whole site because the settings.php gets overwritten every time at publication. I will have to make it outside the settings.php. Is that allowed to modify the code of this free script?
