MyPage WebPart peronalization data read error

Hi,

All of a sudden WebPart peronalization data read error issue has cropped up on clicking the MyPage link. Following error message is displayed:

Value cannot be null.
Parameter name: enumType

[ArgumentNullException: Value cannot be null.
Parameter name: enumType]
   System.Enum.ToObject(Type enumType, Int32 value) +9733710
   System.Web.UI.ObjectStateFormatter.DeserializeValue(SerializerBinaryReader reader) +783
   System.Web.UI.ObjectStateFormatter.DeserializeValue(SerializerBinaryReader reader) +729
   System.Web.UI.ObjectStateFormatter.Deserialize(Stream inputStream) +141

[ArgumentException: The serialized data is invalid.]
   System.Web.UI.ObjectStateFormatter.Deserialize(Stream inputStream) +205
   System.Web.UI.ObjectStateFormatter.DeserializeWithAssert(Stream inputStream) +36
   System.Web.UI.WebControls.WebParts.BlobPersonalizationState.DeserializeData(Byte[] data) +180

[ArgumentException: Cannot deserialize the blob of personalization data associated with the current page.
Parameter name: data] . . .

Seems like personalization data has got corrupted somehow. Any idea when this happens and any solution to rectify it or atleast reset the personalization data.

Thanks,
Anurag

You should be able to reset from MyPage using the trash can icon and switching between user scope and shared scope but if the error prevents that you could run a query to delete data from the mp_SitePersonalizationAllUsers and mp_SitePersonalizationPerUser tables

Hope it helps,

Joe
