RE: it threw up this error message when I tried to install it
Try as I might, I was not able to replicate, on you site or mine :(
RE: well, unless you did, it does appear that the User Switching plugin is installed
Nope, I did not install. The error must have occurred after User Switching was already activated. Which would make sense because that part of the Connections code only runs when doing plugin update checks on the Plugins admin page.
RE: would you suggest that i should export all the connections data in a csv file and then delete completely the connections plugin — and then after deleting the connections plugin, reload it fresh and import the csv file of data?
No, definitely not. I did log back in this morning and switched accounts between all admins and I was not able to replicate the issue. I was always able to filter by all categories.
Try visiting the page with your account with a private browser window. Does that fix it?
