Hi, as per your suggestion I tried posting in Classifieds. I created a new topic, gave it a title, wrote the post, added tags and said Post.the following error came up: An unexpected error was returned: '187726 and when I tried a few minutes later it said the same thing but error number was 187732 - I have no idea. Article did not get posted.
I had the same problem but then I pushed review first and then did post and it worked. Try to review your post first.
