SharePoint 2003: Web Part Error: This page has encountered a critical error. Contact your system administrator if this problem persists.

Error:

 

Web Part Error: This page has encountered a critical error. Contact your system administrator if this problem persists.

 

Description:

 

We tried to upgrade SPS 2003 to MOSS 2003 using in place upgrade which was a disaster. Fortunately it was our development serverJ. We uninstall SPS 2003 and reinstall SPS 2003. When we try to open the portal main page “http://portal/default.aspx”, found the error “Web Part Error: This page has encountered a critical error. Contact your system administrator if this problem persists.” on every web part. Other links like “Sites” were also not working.

 

Resolution:

 

It turns out that our SharePoint Central Administration and Virtual Server was running under ASP.Net 2.0…… We changed it back to 1.1…… through IIS and everything was fine.

    Hi,

    This problem was caused by an incorrect entry in web.config. If you have backup of your webconfig restore it back you will get your working site back otherwise check again what you added in web config(mostly in safe control).

    hope it helps.

    Kuldeep was right. The “web.config” file is the FIRST thing to check.
