Your profile says you only made 20 Forum Posts, so that sounds like an oddly high chance of error. (I can't remember that this would have happened to me at all across my use of the forums on Windows/Linux and Firefox/Chrome.) To narrow down the source of the problem, could you description your setup(as asked below), and follow the default troubleshooting steps(below) first, and then answer a few of my questions? Detailed description of the problem (does pressing the "Submit Post"-button refresh the page but your new post doesn't appear? Or is pressing the button sometimes doing nothing, and you need to press it more than once? Is this only with replies, or also when submitting new posts? Have this happened only on the general forums, or also when posting in some campaign's forum as well?) Minimum number of steps to reproduce the problem Bug Report Template : Description of setup Browser + Version Browser Addons/Extensions Operating System Bug Triage Results Please carefully work through to the first three steps of our guide to Solving Technical Issues : Step 1: Make sure to use the right browser Please check if these issues persist when using both Chrome and Firefox. Step 2: Ensure that there are no extensions/addons interfering with Roll20 Please disable all add-ons/extensions. Step 3: Clear your cache If none of the above succeed in resolving the problem, please thoroughly work through Step 4 . (Don't forget the complete Console Log!) Do you have a stable internet connection, or do you at times have interruptions? Could you estimate how many times this have happened to you? Roll20 claims you only made 20 post, so it sounds like the failed posts doesn't increase the counter on your profile. Do you have a link to the old "replies disappearing" thread?
