Errors in connector.aspx

I have a big trouble. I'm receiving a lot of errors of such contents:

Re: Errors in connector.aspx

Also problems for me with this issue since I installed CKFinder.

Is there a solution for this already?

Re: Errors in connector.aspx

I have added this issue to our internal tracker, it should be fixed in the next release.

Hi Wiktor,

Can you please tell me what is causing this error or tell me when a release with the fix comes available?

Some of our CMS customers do have serious problems with this issue.

Thanks,
Marc

Re: Errors in connector.aspx

we are getting this as well, but only for one install - its fine for others. I'm also having problems replicating it locally.

Is there any indication of what is causing it? It might just require a try....catch block in ThumbnailCommandHandler.cs, maybe around one of the DateTime.Parse lines such as this one:

if ( cachedTimeStr != null && cachedTimeStr.Length > 0 )
{
   DateTime cachedTime = DateTime.Parse( cachedTimeStr );

   if ( cachedTime >= thumbfile.LastWriteTime )
      is304 = true;
}

Re: Errors in connector.aspx

I've modifed line 112 of /Connector/CommandHandlers/ThumbnailCommandHandler.cs to this:

if ( !is304 )
{
   string cachedTimeStr = Request.ServerVariables[ "HTTP_IF_MODIFIED_SINCE" ];
   if ( !string.IsNullOrEmpty(cachedTimeStr) )
   {
// #MOD try catch block to try and fix strange DateTime error
       try
       {
DateTime cachedTime = DateTime.Parse(cachedTimeStr);

if (cachedTime >= thumbfile.LastWriteTime)
    is304 = true;
       }
       catch (Exception)
       {

is304 = false;
       }

   }
}
