Categories lost for all sites


We have a large multi-site installation. Today a user reported that all her categories were gone. I checked and this is true on all the sites. The Dashboard/Right Now box shows the categories but it you go to the Categories list, it is empty.

Anyone ever come across something similar? Problem with the database?

Thank you,

    Hi Sylvia,

    Yikes, I’ve not come across that one before! Have you checked out your database at this point to see if the categories are still there?

    Should be in wp_x_terms, where x is the respective blog id. If you’re using Post Indexer, you should have the terms all available in wp_site_terms.

    If the data’s gone from there, it’s just weird and I could only imagine that would have been done manually somehow.

    Perhaps you could check with your host as to what types of backups they might have?



Thank NAME, for their help.
