Hello Itsjustme -
I am sorry to hear that you ran into some difficulty posting. I am not aware of any issues on our end that would have resulted in difficulty with working on or posting listings. I checked with our engineers and we have no indicators that there was any sort of widespread issue occurring and the site is operating as expected at this time so it is unclear what you encountered.
If you are still running into any difficulties please let us know the details of what you are running into and what you are working on when it occurs in a support case so we can have a look into it for you.
