I am not sure what happened. I upgraded to 2.8.4 about 2 weeks ago. About two days ago I lost all my tags, categories, links and some sidebar functionality. I did not save a backup as my host service does that and if there is an issue I can usually restore the site. When the problem happened I contacted my service but as can sometimes be the case the guy there did not restore the site to a week or go or know how to deal with the problem. So now am I stuck with no tags or categories or ability to display links in my sidebar?
I can see my tags on my tag page in the admin area and my links as well, but all categories are gone. On my edit page I can see no categories. The field is blank. If I try to add a new category nothing happens. Same with tags. I can enter a tag but it never appears. My link widget just not work at all.
I will not get any help form the tech guy there. Maybe the guy I deal with usually will be back from vacation soon and something can be sorted out, but why can't I at least add new tags and categories? Why can't I display my blogroll?
I have nothing to restore it seems. I will now do my own database backup when I upgrade (should have already I guess).
Anyone know why this is? the topic appears to unresolved in the forum posts.
