I have turned on Enterprise Metadata and Keywords in several of my lists and libraries. Users were able to add keywords until yesterday since then the field is appearing as disabled and users are not able to add any keywords.
This issue occurs for all the lists where the field has been added. Nothing was changed in the sharepoint configuration to cause this.
Please let me know how I can find out and rectify this issue. or point me to where to look for the issues.
Any help is much appreciated. Thanks in advance.
