Hello I'm seeing the following message in event viewer consistently. i don't know what is the impact of this issue and why it keeps coming? Can anyone let me know? Event Type:ErrorEvent Source:Office SharePoint ServerEvent Category:Publishing Cache Event ID:5785Date:5/1/2007Time:6:18:31 AMUser:N/AComputer:HRITO0101Description:Unable to connect publishing custom string handler for output caching.

Thanks Krish

I am getting the same 5785 errors.Did you find out what was causing these errors? Thanks, Tony

This had me troubling for quite a while and looking on the Internet didnt really give any real solutions. In my case the errors were caused by a custom Web Service that I added to SharePoint. When one of the Web Parts called the Web Service an event log entry was written: Event Type: ErrorEvent Source: Office SharePoint ServerEvent Category: Publishing CacheEvent ID: 5785 ProfilePictureEventHandler A SharePointLibrary event handler to automatically link a picture to a MOSS 2007 User Profile. The file names must be of the following format: [accountName].[ext]

I'm still working on mine.

Looks like it was the Metalogix Team Migration extensions. No errors since uninstall.

tryto modify theweb.configof the Web Service application. Remove thePublishingHttpModulemodule that was added by the root web.config:<httpModules><remove name="PublishingHttpModule" /> ...</httpModules>

Hello, Thanks for this Post, but if i can add a comment :For an application Sharepoint/Custom.When the errors appears for /_layouts/images/*.gifWe must add :<httpModules><remove name="PublishingHttpModule" /></httpModules>on the application Web.configin the section <locationpath=''_layouts/images"/> (just before </system.web>)

Go to your web.config file and remove the following line if it already exists from the httpHandlers section: <remove verb="*" path="*.asmx" /> After removing it, you should no longer get that error.Dennis Alzoubi

Hello. I am getting a quite similar error to yours. In my case, the file is an aspx file, but other than that (and of course the computer and path difference, etc.) they are the same.I see further down the thread, the discussion turns to a similar error relating to a .gif file. I was uncertain whether solutions would differ between an executable web part and a display only .gif file. Has anyone else with this problem found a solution?The weird thing is that the web part in question is actually displaying its contents as expected.

I had accidently deleted the global.asax file and this error started occuring.

I just performed an IISRESET and this solved the problem.
