What is SharePoint?
The most common errors reported are below along with steps to help resolve the issue.
Library Not Registered: This error has been reported for users who have recently performed an upgrade in Office. Like many Java issues with upgrades and updates, cleaning up leftover program pieces along with restoring default settings has been successfully used. Also successful has been the use of Office’s self-diagnosis and repair feature.
Object Expected: if ‘Object Expected’ error arises in the search box on a created page, you may find that the functionality of the search box is still there, but the error message remains. To solve this error, you may want to try the ‘Hit and Trial’ feature and check to see if all the placeholders are properly configured. SharePoint may be looking for a specific type of term and not finding it although the value is there.
Access Denied/Undefined Is Null or Not an Object/Permission Denied: Most of the time when these errors come up, it is due to updates that need to be installed. If you are not installing updates automatically, you can search for the available updates or review them in the log to determine if you wish to install all or just some of them.
Troubleshooting and Correcting
If you are getting an access denied error message when you are using the program, here are some basic suggestions.
Are your references correct?—Java’s file structure requires exact references to available files and resources. If those references or paths are not correct, any number of errors can arise.
Are permissions correct?—Perhaps you have inadvertently deleted or changed access rights to the users when editing a master page or applying an update. Trying the actions with different user profiles or on different machines will establish this as a possibility.
SharePoint has self-diagnosis tools and there is a very large community of talented developers and administrators out there to seek solutions to errors we have not covered here. With all the machines and configurations, there could be thousands of differing answers to any group of similar issues. This will keep you from using your time in a trial and error pursuit of an answer.
