Just tried it on mine. Everything work fine. There may be something else going on. You may want to post this in the troubleshooting section so Ross will see it. I don't see him in the theme section much. Of course he want be back on until Monday.

You might be pulling up a cached version of the site, clear your site cache with dev mod on, and then also clear your browser cache as well.  Let us know ;)

Good point. I didn't think about that.

I managed to change Header and Logo images by uploading the new ones in the ow_static folder:( /public_html/ow_static/themes/simplicity/images/ ) and NOT in the main ow_themes folder: ( /public_html/ow_themes/simplicity/images/ )

That means that your static content is not being replaced when you clear your cache using dev mode, which is why i recommend that extreme cache plugin, its free and it does a fair job, sometimes better than the manual way. 

The general.html, and dndindex.html are all jacked up in the Simplicity theme. I've suggested some fixes to get the code fixed. I've just went back through it again, and made the attached changes in the 1.8.3 version. There were to many moves, and adds to list them all. I've attached the two files with the mods. Take a look. Copy your original files, and place them in another folder, and replace them with these. Let me know what you think.

If you do this, don't forget to set dev mode to true, and refresh you site for the changes to take affect. Then set dev mode back to false. I've forwarded this on to 'Ross as well.

With the mod above; I was able to change the header pic, and the logo image with no issues. It also hides the header image when you click on "customize this page" on the index page.

Darryl B but how i can mod that ?
