actually am using 2.7.1
but it happened in 2.7 also...
i can post
'Seriously... Read the third sentence of the paragraph.
<img src="http://i93.photobucket.com/albums/l48/NHL23/Football/rps_error.jpg" border="0" alt="2009 Rookie Photo Shoot Sweepstake">'
just fine, but if i post
'<IMG alt="Jelly Belly Easter " border="0" src="http://jellybelly.cachefly.net/Jelly-Belly/Affiliates/Creatives/Easter/300x250.gif"><IMG border="0" width="1" height="1" src="http://ad.linksynergy.com/fs-bin/show?id=hBOUIu9/fMs&bids=170349.10000044&type=4&subid=0">'
it kicks me out to a error page.
I even was able to post
'<center><object width="488" height="117" data="http://a405.g.akamai.net/f/405/11649/1h/pepsicoinc.download.akamai.com/11649/sites/dewmocracyvoltage/downloads/badges/voltage_badge1.swf?user_nm=nhl23&enc_yid=.bVsjEOGV0lT1lK5j4c-" type="application/x-shockwave-flash"><param name="allowFullScreen" value="false" /><param name="allowscriptaccess" value="sameDomain" /><param name="quality" value="high" /><param name="src" value="http://a405.g.akamai.net/f/405/11649/1h/pepsicoinc.download.akamai.com/11649/sites/dewmocracyvoltage/downloads/badges/voltage_badge1.swf?user_nm=nhl23&enc_yid=.bVsjEOGV0lT1lK5j4c-" /><param name="allowfullscreen" value="false" /></object></center>'
and it showed up as well.
k it sends me to
'http://www.cardstuff.com/wordpress/wp-admin/post.php'
Which exists on my server, but ends up being an error page.
ERROR TYPE FILE TO DISPLAY
400 - Bad Request
401 - Authorization Required
403 - Forbidden
404 - File Not Found
500 - Internal Server Error
501 - Not Implemented
507 - ASP Engine Error
all are set to http://www.cardstuff.com/404error.html
changed themes, still doesn't work.
I can post the sample post above with no problem, so it would seem to be a local issue rather than a code bug.
Check without plugins.
Then re-upload the WordPress files from a freshly-downloaded source zip.
Plugins don't seem to be the problem, so I guess freshly-downloaded source.. i did the 2.7.1 in the automatic thing so /shrug.
I copied
HTML clipboard .style1 { text-align: center; }
<div class="style1"><a href="http://click.linksynergy.com/fs-bin/click?id=hBOUIu9/fMs&offerid=170349.10000044&type=4&subid=0" target="new"><img src="http://jellybelly.cachefly.net/Jelly-Belly/Affiliates/Creatives/Easter/300x250.gif" border="0" alt="Jelly Belly Easter " /></a><img src="http://ad.linksynergy.com/fs-bin/show?id=hBOUIu9/fMs&bids=170349.10000044&type=4&subid=0" border="0" alt="" width="1" height="1" /></div>
and it worked... then I deleted
HTML clipboard .style1 { text-align: center; }
<div class="style1"></div>
and everything works fine.
