I then oh-so-intelligently reasoned that this plugin couldn't be the cause of the problem, so I moved on...</p> <p>I couldn't just disable all plugins and test with a default theme because of the existence of private forums. Finally, I moved the database to a private test server (and used a HOST file) and went through all the plugins carefully one-by-one until the problem was fixed.</p> <p>Let my idiocy be a lesson for others: wrap your plugin function calls with function_exists wrapper! :-) </p> http://bbpress.org/forums/topic/error-after-new-post-all-of-a-sudden#post-16023 Wed, 07 May 2008 12:11:24 +0000 chrishajer 16023@http://bbpress.org/forums/ <p>Hey, I thought you said you "disabled plugins and Akismet, and the problem didn't go away." Maybe you didn't disable this Email Notifications one?</p> <p>Glad you solved it, in any case. </p> http://bbpress.org/forums/topic/error-after-new-post-all-of-a-sudden#post-16019 Wed, 07 May 2008 08:47:05 +0000 bobbyh 16019@http://bbpress.org/forums/ <p>Thanks Chris! All my PHP scripts were OK (no syntax errors), but eliminating one more possible cause is always helpful. :-)</p> <p>It turns out that this Email Notifications plugin (http://bbpress.org/forums/topic/plugin-post-notification?replies=44) was causing the problem. After disabling that plugin, there are no "delays in posting" and there is never a 500 error. There must be a scaling problem with the plugin that started after the tables hit a certain size...</p> <p>Thanks again for your help, Chris! :-) </p> http://bbpress.org/forums/topic/error-after-new-post-all-of-a-sudden#post-16016 Wed, 07 May 2008 02:23:59 +0000 chrishajer 16016@http://bbpress.org/forums/ <p>How about configuring custom logging temporarily, just to be sure you are seeing the logged errors? </p> <p><a href="http://us3.php.net/set_error_handler" rel="nofollow">http://us3.php.net/set_error_handler</a></p> <p>I think the delay in posting is not due to server load but due to this 500 error. It's thinking about something then it fails.</p> <p>If the script had a syntax error, I would think it would fail more quickly. You can check all your php scripts for syntax errors if you have command line access if you do something like this:</p> <p><code>shell# find . -name &quot;*.php&quot; -print| xargs -n1 php -l</code><br /> (that's "dash n one" and "php dash el", lowercase L)</p> <p>Looks like you're on CentOS so that should work OK. </p> http://bbpress.org/forums/topic/error-after-new-post-all-of-a-sudden#post-16009 Tue, 06 May 2008 22:39:39 +0000 bobbyh 16009@http://bbpress.org/forums/ <p>Thanks for thinking about my problem, Chris! :-)</p> <p>I don't understand the problem either... I'm sure the PHP errors are being logged. I just triple-checked my httpd.include file, and it has this line: <code>ErrorLog /var/www/vhosts/weddingbee.com/statistics/logs/error_log</code>. This is the location that I've been looking for the PHP errors. There are other PHP notices/errors from this boards subdomain (mostly from bots looking for non-existent Front Page files), but nothing about this error.</p> <p>In the access_log, I do see lines like this:</p> <p><code>74.235.132.92 - - [06/May/2008:04:32:32 -0400] &quot;POST /bb-post.php HTTP/1.1&quot; 500 366 &quot;http://boards.weddingbee.com/topic/second-guessing-everything&quot; &quot;Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 1.0.3705; .NET CLR 1.1.4322; Media Center PC 4.0; .NET CLR 2.0.50727)&quot;</code></p> <p>However, that's not what we want...</p> <p>Last night, I did some searches and found <a href="http://us.php.net/manual/en/function.error-log.php#52078">this comment on php.net</a> which said that the two reasons for a missing error in the error_log were "(1) you did not configure error_log output in php.ini, and (2) the script has a syntax error and did therefore not execute." However, the script does appear to be executing at least partially, because the post/comment <em>does</em> post. Also, if you visit the bb-post.php page (http://boards.weddingbee.com/bb-post.php) directly, the page does execute (with a <code>die</code>).</p> <p>I too am confused by why the POST takes such a long time. The load average for the webserver and the database server are fairly low... </p> http://bbpress.org/forums/topic/error-after-new-post-all-of-a-sudden#post-16007 Tue, 06 May 2008 22:19:53 +0000 chrishajer 16007@http://bbpress.org/forums/ <p>I made two test posts. The both resulted in 500 errors, but they also both appeared to go through. They also took a really really long time, like something is going on in the back end. Are you sure the PHP errors are being logged? A 500 error should go *somewhere*. </p> http://bbpress.org/forums/topic/error-after-new-post-all-of-a-sudden#post-16006 Tue, 06 May 2008 22:16:11 +0000 bobbyh 16006@http://bbpress.org/forums/ <p>I turned off permalinks (set it to <code>false</code> in config.php) and the error still occurred... </p> http://bbpress.org/forums/topic/error-after-new-post-all-of-a-sudden#post-16005 Tue, 06 May 2008 22:12:57 +0000 chrishajer 16005@http://bbpress.org/forums/ <p>Is it a mod_rewrite issue causing the problem?

Previously, my bbpress forum was working perfectly. However, over the last few days, I have verified that if you submit a new post or leave a comment, the browser takes you to <a href="http://boards.weddingbee.com/bb-post.php">bb-post.php</a>, where the page hangs. You can verify this on my forum using user "testuser" and password "test123".</p> <p>There are a few weird things about this:</p> <ul> <li>I hadn't touched the server for some time prior to this sudden problem, so it's weird that the problem started, since I hadn't changed anything</li> <li>I've been running two bbpress forums authenticated against the same WP user table. The problem is only with the <a href="http://boards.weddingbee.com">first bbpress installation</a>, while the <a href="http://classifieds.weddingbee.com">second bbpress installation</a> continues to work with no problems.</li> <li>When you post, the browser returns a 500 internal server error, and doesn't display a "die" message, e.g. "You need to actually submit some content!"</li> <li>Although the browser returns a 500 internal server error, the posted content does go through.</li> </ul> <p>I've hand-inspected <a href="http://boards.weddingbee.com/bb-post.php," rel="nofollow">http://boards.weddingbee.com/bb-post.php,</a> and it has exactly the same PHP code as <a href="http://classifieds.weddingbee.com/bb-post.php." rel="nofollow">http://classifieds.weddingbee.com/bb-post.php.</a> I've tried everything I can think of... I disabled plugins and Akismet, and the problem didn't go away. (I've turned them back on.) </p> <p>I'm using bbPress 0.83, with bb_db_version 788. I haven't upgraded to bbPress 0.9.0.2 yet because I've integrated my Wordpress 2.33 install with two bbPress installs and a Mediawiki install, and it will be a ton of work to reintegrate. However, that is the next step...</p> <p>Does anybody have any ideas? :-) </p>
