Made the last update to 4.7.16 a few days ago and all seems to work fine, but users complain about firefox and the activity streams.
Using "All Acitivity" you click on a thread, read it in the same tab and go back to "All Activity" - with firefox all looks the same, the thread is still bold, but with safari it's narrow.
Using "Unread Content" the same way - with firefox all looks the same, but with safari it's gone.
Funny about that is using firefox here at ivisioncommunity.com it works as it should. Same as safari does.
We have MySQL still at 5.7 and PHP still at 8.0, but i don't think that makes any difference. A Redis Cache could maybe, but i don't know how.
Emptied all cache in "Get Support", but no difference to see.
Any ideas anyone? π
