  The latest version of RadEditor 7.1.2 introduces a bug "RadControls folder not found", which is due to a modification in the RadControls\Editor\Dialogs\blank.html file.
  
  If you experience this problem on your side, you can easily fix it by using one of both solutions below:
  

  1. Copy and use the RadControls\Editor\Dialogs\blank.html file from the previous version 7.1.1 of RadEditor. For your convenience I have attached this file to my message.
     
     OR
     
     
  2. Open the RadControls\Editor\Dialogs\blank.html and replace its content with
     
     <root></root>
     
     Save the file.

  Please, also make sure that the blank.html file has the needed full ASPNET / NETWORK SERVICE permissions.
  
  The problem was fixed in our internal build of RadEditor and it will not exist in the next hotfix of the control.

  just a small remark: seems you forgot to attach the previous version of the file blank.html to your post.

  Just a quick note.  The blank.zip you attached is the wrong version of the file.  I replaced my own blank.html with the one in your zip and it didn't work.  I used your <root></root> suggestion instead and that worked great!
  
  Thanks for posting this info.  I was going crazy trying to fix this one tonight.  I intially thought one of the programming changes I had made was causing this error as I was only seeing it when debugging under Medium Trust.

  Hi Jeffrey,
  
  I am glad that you have fixed the problem.
  
  The attached version of the blank.zip is taken from RadEditor 7.1.1 installation and it should work. Nevertheless, I have attached the latest version of the blank.html file which only contains <root></root> tags.

  I'm not sure why, but the 7.1.1 version didn't work for me.  Only the <root></root> version did.  Is it possible it has something to do with Medium Trust?  I was only seeing this error when debugging in Medium Trust.

  Hi Jeffrey,
  
  You are absolutely correct that the content of the blank.html file (v7.1.1) leads to the
  

  the RadControls folder was not found

  error under Medium Trust:  <trust level="Medium" originUrl=""/>.
  
  The problem could be easily fixed by replacing the blank.html content with <root></root> tags.
  
  I appreciate your help on reproducing this problem and I updated your Telerik points.
  
  Kind regards,
  Rumen

  Hi,
  
  I am using the RadEditor (trial version) 7.1.2 and after making the suggested changes neither corrected the problem.  The editor RadControlsDir directory is set to ~/RadControls/.  I have copy of the RadControl directory in my project solution.  Please advise.

  Hi Mark,
  
  If the RadControls folder is placed physically in the root of your web application then you should not set the RadControlsDir property, because its default value points to that location. You should make sure that you have copied all the folders and files in the RadControls/Editor folder too.
  
  My suggestion is to try the instructions provided in the following KB articles: Changing the default location of the RadControls folder and Which files and folders are mandatory to be on the server for RadControls to function. If the problem still persists please open a support ticket and send a sample working project that demonstrates the issue. We will need the bin and RadControls folders as well as two screenshots of your web application structure in IIS and Windows Explorer. Once we reproduce the issue we will provide a working solution.
  
  Best regards,
  Rumen

  For some reason this bug only showed itself when I was not connected to the internet.  What is going on behind the scene that makes this work when connected the internet?  I did replace the contents of blank.html as instructed which solved the issue, but I still am a little curious as to how this was only a problem when no internet connection was present.

  Hello Ryan,
  
  Generally speaking the problem was in RadEditor throwing wrong exception when certain conditions were met - no internet connection is one of them. It is fixed now and with the next version, you will not need to modify anything.

  This doesn't explain why it wasn't erroring while connected the internet.  It was obviously trying to use the blank.html in the RadControls folder on my local machine when not connected to the internet, but while connected to the internet where was it going to get a working version of the blank.html file?

  Hi Ryan,
  
  In version 7.1.2 of RadEditor, we make the blank.html file XHTML compliant by replacing its content with these tags:
  
  <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
  <html xmlns="http://www.w3.org/1999/xhtml" >
  <head>
      <title>Blank Page</title>
  </head>
  <body></body>
  </html>
  
  So when the server hosting the editor application is not connected to Internet, then the blank.html file is not able to
  reach the following internet address, <html xmlns="http://www.w3.org/1999/xhtml" > which is causing the error.
  
  When the server is connected to internet, then everything is fine, because the <html xmlns="http://www.w3.org/1999/xhtml" > page is accessible.
  
  By replacing the blank.html file contents with <root></root> tags, you will ensure that the editor will not need to validate it from the internet and you will no longer get exceptions.
  
  This change will also affect the loading time of the editor and it will increase its loading speed.

  This bug also causes big slowness in applications!!!
  After a day of work to find the problem of an unexplainable slowness of my application, only when I have disabled my lan, I have found the error.
  
  Perhaps this problem needs a email-campaign among your customers.
  
  Best Regards.

  Hi Andrea,
  
  Please, accept our sincere apologies!

  We truly apologize for the inconvenience this has caused and we would like to assure you that if such a problem arises in the future, we will do our best to notify our customers about the issue by posting a sticky note, by blogging and uploading the hotfix right away on our site.

  Ack, i wish i would have found this thread *before* I tried to do a presentation to a committee of an organization i was proposing some development for.  I tested the app on my laptop before I went to the meeting, and everything was great.  I got to the meeting (no internet connection) and when I accessed the page that had the RadEditor on it, it displayed a nice server error message.  Very embaressing...
  
  Anyway, thank-you for posting this work-around.  It works perfectly.

  This error still exists in v7.2.1 of RadEditor (just installed Q2 2007 SP1). I had to replace the "blank.html" content (HTML template) with "<root></root>" and only then it started to work :(.

  Hello Georg,
  
  I checked the contents of the blank.html file of the RadEditor 7.2.1 installation and they were:
  
  <root></root>.
  
  Are you sure that you are not using an older version of the blank.html file?
  
  Kind regards,
  Rumen

  The thing is that now I'm using the new "blank.html" file - but I had to replace previous content (simple HTML template) with "<root></root>" to get it work. I'd like to have my template back in that file if it's possible. Because now, with this new "blank.html" content - after saving the file I get only HTML tags inside, but no header or footer (<html>, <body>, etc.)

  Hi Georg,
  
  

  We do not recommend using the blank.html file for template store purposes, because it is a system file of RadEditor.
  
  However, if you want to use it despite our suggestion, then make sure that the following lines do not exist in the blank.html content (they were the reason for the problem in v7.1.2):
  
  <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
  <html xmlns="http://www.w3.org/1999/xhtml" >
