I've tried modifying the global.asax file with empty spaces as suggested, but I'm still getting the same error. Additionally, I accessed the log files and received the following message:
"Error while running the 'Keep alive' schedule task. The remote server returned an error: (404) Not Found.
System.Net.WebException: The remote server returned an error: (404) Not Found. at System.Net.WebClient.DownloadDataInternal(Uri address, WebRequest& request) at System.Net.WebClient.DownloadString(Uri address) at System.Net.WebClient.DownloadString(String address) at Nop.Services.Common.KeepAliveTask.Execute() at Nop.Services.Tasks.Task.Execute()"
I'm generating the following error when trying to execute the "re-load plugins List":
We're sorry, an internal error occurred that prevents the request to complete.
Our supporting staff has been notified with this error and will address this issue shortly. We profusely apologize for the inconvenience and for any damage this may cause. You might want to try the same action at later time.
This is the same issue reported by liu698, but the resolution was never posted.
I am using NopCopmmerce 2.60 and have had success installing other plugins.
Like Liu698, my issue is with the Categories Header Menu plugin. Please advise.
