some offer me disable my blugins and try again , i do but nothing changed . still face the problem

i was confused so i was not know where the problem . i was want to put feed count from feedburner in my blog ” money academy” but it still inactive option in my blog feed so i try to activated it but i got this message :

The URL you entered does not appear to be a valid feed. We encountered the following problem: Error on line 650: The markup in the document following the root element must be well-formed.

so what is the problem !

if the feed is not valid , i think that the original feed and feedburner shouldn’t work , but it was work perfectly !!

feedburner give me this link

http://feedvalidator.org/check.cgi?url=http%3A%2F%2Fwww.smasra.com%2F%3Ffeed%3Drss2

when i check my feed ” all feeds as /feed , /rss2 , /atom/feed ” all show error

Sorry

This feed does not validate.

line 619, column 0: XML parsing error: <unknown>:620:0: junk after document element [help]

</rss>

and show me the error source

Source: http://www.smasra.com/rss2

with yellow color i saw the error

</rss>

but where i fix it !

i searched in my wordpress files ” wp-feed.php , wp-rss.php,wp-rss2.php .. ” but not found the file for this code .

after i disappoint i decide to reinstall my blog again because i was sure that my host is clear ” hostmonster ” and my other sites on this host/server work fine and i burned them feeds without problems !

while i make my database backup i wanted to install it by simplescripts , but when i entered the setup area i found that my blog already setup by semplescripts . and a red mark there show that it need to upgrade to next version ” Version 2.7 ” .

i was know that my blog was 2.6 but i wait to see version 2.8 and upgrade , but in simplescripts you install/upgrade your blog with one click so it was easy to upgrade .

i done .. and the problem was fixed . but after that i still don’t know what was the problem , most of bloggers which found this problem don’t know how to solve and after it solved they don’t know how it solved .

i write this just to share me my wonder about this service from feedburner .. now they start to move from feedburner to Google so don’t worry if you faced this problem also if you know how to solve it tell us .
