An error occurred while saving the Web part after modifying the attributes.

Error message: cannot save the property settings for this Web part. exception occurred

Analysis: it is likely that the spsite object is incorrectly parsed when the user writes a Web part.

Solution:

Modify the following programming method:

======================================
1: spsite site = spcontext. Current. Site;
2: // do something with it
3: site. Dispose (); // throw an error upon dispose:

======================================
1: spsite site = new spsite (spcontext. Current. Site. ID );
2: // do something
3: site. Dispose (); // this code will not throw an error on dispose
