garyricke can you check the version for the "Subscriptions" extension is also 1.3.1? (Select extension on the left, then extension version will be in the top right of the screen)

Yes, looks like this extension is 1.31
luceos — can you direct me on how to do that?
garyricke this could also be caused by a very similar issue in fof/follow-tags, which was fixed recently in version 1.1.4. Which version do you currently have of this extension?
fof/follow-tags
1.1.4
ianm Thanks for the suggestion — I'm not even seeing fof/follow-tags as an option in the free version I'm using
Thanks for bringing this to my attention luceos, I didn't notice this discussion. I think that the bugfix mentioned by ianm should be available at FreeFlarum, but I've updated all extensions just to be sure. Please, let us know if the issue persists @garyricke
garyricke free version
There is no paid version of Flarum. Are you hosted on freeflarum?
luceos Yes, we are hosted on freeflarum
garyricke you should seek help in the freeflarum discussion. FreeFlarum is a community operated initiative, we have no insight into the errors and versions in use.
luceos thanks, I'll keep trying
