We have a client using SharePoint 2013 On Premise. They have several site collections, Home, Projects, Teams, MySites, etc.
On the project site they created a site to be used as a template for other project sub sites. When they tried to use the template to create a site, it was throwing an error about the "HashTags" field (or "HashTags0" field) being duplicated.
On inspection, several columns named "HashTags" were listed in site columns. The duplicate column was removed from the site, and upon doing so, they all disappeared. Looking at the site with SharePoint Manager, the fields still existed, all with the
same exact FieldID. This is a production site, so we were hesitant to try and delete these fields using SP Manager, without any understanding of why this was occurring in the first place. I have done some research and searches on the issue, and originally
I was finding a mention of this, but it was in reference to Office365 SP, not On Premise. Now I am starting to see additional posts on the subject, and it seems like a known issue, but to my knowledge, Microsoft (outside of Office365 support) has not
weighed in on the problem.
Now, in addition to the existing issue above, Last week the client expressed a desire to start using Newsfeeds outside of MySites. The Site Feed feature has been turned on at the root of the Site Collection for their Projects site, and also
in a sub site for testing. When a conversation is input the following Error occurs
"We've hit a snag, Looks like the newsfeed was removed from the site, the site was deleted, or there's some temporary network problem. You can try again later or stop following the site from the sites page."
Viewing the ULS logs while trying to post to the newsfeed indicated an error with an invalid Field ID. In researching the mentioned Field ID, sure enough, it is the HashTags field. The interesting thing is the newsfeed works fine on MySites, and within
at least one other site collection in the farm. Also notable, is that in the microfeed list where the newsfeed throws the error, the HashTags column is not present (or at least not from site settings as a site column), while it is displayed as
a site column on the sites where the newsfeed is working.
Has anyone seen this issue, and been able to resolve, or at least determine why the field is getting duplicated to begin with?
Thank you,
