Make Sharepoint show you error messages rather than “An unexpected error has occured” Posted on September 14, 2010 by James Rossiter This involves changing the web.config file (thekid). The solution is to change a single entry in web.config, by modifying the line… <SafeMode MaxControls=“200“ CallStack=“false“… to… <SafeMode MaxControls=“200“ CallStack=“true“… You will also need to set custom errors to ‘Off’ . <customErrors mode=“Off“/> Share this:EmailPrintFacebookTwitterLinkedInGoogleMorePinterestDiggStumbleUponTumblrReddit
