I usually have problems posting when using my iPod. If it's making the page scroll up to the سب, سب سے اوپر after آپ hit enter it's a glitch. If it's saying آپ reached the character when آپ haven't it's a glitch. If you're trying to post on someone's دیوار it could be privacy settings.
I can only post on walls on my iPad. I dunno why but I can't post on them on my PC یا laptop. Its weird. Its probably a glitch with the site but its been like this for awhile. I have read that other users have been reporting similar problems to the fanpop team but still no change.
If its anything like me everytime i try to post the سہارا یا smiley face choices along with the کرائیں جمع یا whatever it says does not دکھائیں up on my pc and laptop but yet i can post on the same users دیوار that I was going to post on with pc یا laptop on my iPad and everything shows up and it posts just fine.
Actually, I messaged Micheal (one of the creators of Fanpop) and he's fixing it right now. It could be the browser you're using یا the "internet security" like Norton آپ may have. It might take awhile but I keep آپ updated.
