I'm working with Sitecore 7.0 rev 131127 and when I tried to go to the Content Editor I'm getting the following error:
But when I try to go to other modules such as Marketing Center, it is working.
I tried the following changing following value to false on Sitecore.Social.config but it didn't work for me.
<!-- Is Profile updating at user login functionality enabled. -->
<setting name="Social.ProfileUpdating.EnableProfileUpdating" value="true" />
Can anyone advise on this ?
This is a configuration issue if I'm not mistaken namely your Lucene Index Configrations files within the App_Config/Includes folder. Most likely the Sitecore.ContentSearch.Lucene.DefaultIndexConfiguration.config file or a custom one created in your solution.
Usually you see these sorts of errors when a TypeConverter is missing from the config, as you can see its referencing the Typeconverter in the StackTrace. E.g. For the index to correctly convert DateTime this line is added to the DefaultIndexConfiguration.config file. Confirm the following line is in your *.DefaultIndexConfiguration.config file(s)
<converter handlesType="System.DateTime" typeConverter="Sitecore.ContentSearch.LuceneProvider.Converters.IndexFieldDateTimeValueConverter, Sitecore.ContentSearch.LuceneProvider" />
It's also worth identifying which Field is causing the error. Perhaps a new field has been added recently to a template or the raw value in a DateTime field is not in the correct format for a DateTime Sitecore stores its dates in ISO 8601 formatted i.e. yyyyMMddThhmmss
