title: DotNetNuke CSS problem on page postback?
body: <p>We're having a very strange problem with css in DotNetNuke.</p>
  
  <p>It seems that with any of our custom modules, if a user clicks to postback 9 times the skin css is removed  and the page becomes rather ugly. Looking at the source the tags with the urls to the css files are gone. After one more click making 10 postbacks, any custom css files we've added are removed as well. It seems that sometimes the css will come back after more postbacks but other times it will not.</p>
  
  <p>what you click on doesn't matter, just the amount of postbacks. However we have another server that on some days will behave fine, and others will have the same behavior.</p>
  
  <p>We can't narrow it down to anything our modules have in common. It happens in modules that do not share any code, but somehow happens in all our modules that we've tried but not in any other modules that come with DNN.</p>
  
  <p>Though experimenting we've also found you can postback say 8 times leave the page and come back, you then can postback 9 more times before the css will be gone.</p>
