I had a hair across my ass around 6a and decided to just sign up for A2Hosting and move the whole damned thing. Insomnia is a ripe bastard and so am I.
I hadn't used Tapatalk in several months. I had forgotten my password and was doing using my phone's browser. I reset the password a couple of days ago. I'm not finding it as convenient as I used to. It's got too much extra stuff on there now and seems too needy. It's always asking me to receive notifications about everything.
I have no issues with alerts or permissions from tapatalk. It asked me once when I installed and gives me alerts as appropriate. Perhaps the Android implementation is not as smooth.
I use the browser on my PC. Don't need alerts there.
Those things may have been disabled in the theme by request and came back when I upgraded Casual to 1.5.14 too... Not sure. I was able to update the theme AND the whole forum at the same time.
Working on improving the old SBS site right now, then maybe I can get up to PHP 7. LOT of progress though.
I believe we already have embed support for at least Facebook, Dailymotion, Youtube, and a few others. Not sure if Twitter is in there. Try posting a public one and see what happens here.
