I have made sure that the application pool user has the modify privilege and the folder mentioned is existing in the domain. I can't track the issue down, and the error is filling up Event Viewer. Any help is appreciated.

Hello Chris,

Thank you for the update. Is there any way to fix this without upgrading the DNN version. I have made sure that the file permissions are set properly and correctly for those folder. I have tried reset the permission for the application pool user for the entire httpdocs folder. Is there any other possibility or areas we need to check? Thank you for your help.
