Can’t edit postage so cannot list ? Description in listing disappears

[chrissyjo88]

Hello please help. New seller here just listing a few things from home and had a few sales with some issues. 
 when I write the description half of it disappears when listed. I revise and redo and same again ??

also now I have to enter in postage measurements, no matter what I put nothing gets accepted. I can longer list anything now. 

before it would let me enter my own cost but that’s now gone

Use flat rate postage to enter your own price. You won't be required to give dimensions.

My descriptions seem to be working, BUT if you have an adblocker they might not show. Try turning your adblocker off. It won't make much difference - most of the junk on your listing is embedded and adblockers don't pick it up.
