I have SharePoint site which was working fine. My site has custom page with custom visual web parts. Suddenly i am getting Web Parts Maintenance Page error when accessing my page. I tried to find any clues in SharePoint log files but i can't find out the reason for this error. Can anyone tell me the possible scenarios for this kind of error?

Actually the reason can be thousand. Are you using custom web parts? What that does?

Usually into ULS log you have all the reason about errors.

I suggest to you to use something like this: https://sharepointlogviewer.codeplex.com/

or this:


to understand what's going on.

  • I am using custom web parts only. It just loads grid with data from database. I have checked using ULSViewer, but could not find exact reason. Do i need to consider all category and levels in log file?

  • We are not getting this issue in our dev env. This issue occurs in production side and we have only sharepoint log files to find the issue.
