Christian,
1. Which version of Cute Editor are you using?
2. Can you set up a temp file location then try again?
3. If you still have problems, please read the following article:
How do I handle a large file upload?
The httpRuntime web.config element controls settings about how ASP.NET processes requests, including maximum request length. It is controlled by the following attribute:
maxRequestLength
The maximum allowed request length that will be handled, in kilobytes. Defaults to 4096 (4 MB).
Here is an example with a 1GB request length:
<httpRuntime maxRequestLength="1048576" />
IIS7 and large files
By default in IIS 7 requestFiltering has the MaxAllowedContentLength property enabled. It specifies, in bytes, the maximum length of the content in a request. The default is 30,000,000 (approximately 30 megabytes.) To change this value you must edit the following file:
%windir%\System32\inetsrv\config\applicationHost.config.
In the ApplicationHost.config file, locate the <requestLimits> node.
Modify the following code.
<requestLimits maxAllowedContentLength ="10000000" />
