Whenever I try to add/modify filters, it either doesn't load it or takes way too long. I've tried on different browsers and logged out and logged back in.
Which browsers have you tried this on? Please try also to clear the cache for the browser you are using and try again.
I've tried this on Chrome and Firefox. I've also cleared the cache and still nothing. Its stuck and gives that loading symbol on the top right.
This was working perfectly 2 days ago. Has the upgrade slowed the system down?
We are now having server issues, and this is probably the cause, we hope to have a fix soon.
