This often happens to me. The only way I've found to fix it is to wait. Within a week it corrects itself.
Believe that its caused by some part of the site updating itself. Someone finds that they made a mistake and correct it(;-(.
We specifically block Tapatalk using Tapatalk's servers for posting images...
Why? Because if we don't do that - then your images that you place in your posts here count against your (free limited) Tapatalk "allowance" hosted on Tapatalk's servers - then later on when you clean them up and the wonderful picture that you took of that rare razor is gone (or you pay Tapatalk a wedge of cash to expand your storage on their servers). Not read their small print but quite possibly they have a clause that takes all the rights to monetisation too. We at TSR don't have such a clause, nor will we ever have.
If you upload as an attachment it should work (and attach it to our server) - or maybe you need to post "in line" - I can't remember - it's an option within the app on your device(s) that you set though.
