    XSLT error when upgrading from 4.7.2 to 4.8.1

    I got this error when trying to visualize my xslt.

    System.NullReferenceException: Object reference not set to an instance of an object. at umbraco.macro.GetXsltExtensionsImpl() at umbraco.cms.businesslogic.cache.Cache.GetCacheItem[TT](String cacheKey, Object syncLock, CacheItemPriority priority, CacheItemRemovedCallback refreshAction, CacheDependency cacheDependency, TimeSpan timeout, GetCacheItemDelegate`1 getCacheItem) at umbraco.macro.GetXsltExtensions() at umbraco.macro.AddMacroXsltExtensions() at umbraco.macro.GetXsltTransformResult(XmlDocument macroXML, XslCompiledTransform xslt, Dictionary`2 parameters) at umbraco.presentation.umbraco.developer.Xslt.xsltVisualize.visualizeDo_Click(Object sender, EventArgs e)


    Does anyone know how to fix this?

    Hi Sherry,

    Can you please double-check that you didn't overwrite your "/config/xsltExtensions.config" file.  

    It could be that you are missing one of it reference in that file or you might have nothing in it.

    Are you using uComponents XSLT extensions?
