marvo im getting issues with tapatalk as well saying failed to connect to server? wierd thing is it still adds my posts.Hi Tel, I've moved your thread to keep all forum technical issues in the same place.
I'm not sure what's causing the 404 errors but if you just installed AVG and it started happening then maybe uninstall AVG and see if it stops. I haven't seen any other posts about similar problems yet so I'd say it's a good bet it's something on your local PC.
im not sure if it is down to an antivirus because its on a mobile phone
