Today I started my adventure with the Sharepoint :)
At the beginning I can not add link to the list becasue this message
appears:
"Cannot make a cache safe URL for "SpellCheckEntirePage.js", file not
found.
Please verify that the file exists under the layouts directory. Web Parts
Maintenance Page: If you have permission, you can use this page to
tem****arily close Web Parts or remove personal settings. For more
information, contact your site administrator.
Troubleshoot issues with Windows SharePoint Services".
To be honest I don't know what does it mean? Could you help me?
