I recently took over a site with relatively high usage that uses WordPress as its CMS / platform. We publish new content to the site on a regular schedule.
Our editors are having problems entering content on the site. After initially saving their article, when they insert additional content and hit the “Update” button, sometimes content disappears.
There is no clear pattern to the loss, except that the longer the additions, the more likely the changes will be lost. The normal threshold seems to be around 500 words, but sometimes much shorter changes are lost.
I have no idea why this is happening. We have 4000-5000 articles in our database, and now WP has just decided to crash. It is only happening on our production server. We can not replicate the bug yet on out staging or development environments.
Here is what I’ve tried so far to fix the problem:
* Checking the error and access logs
* Checking the mysql log
* Clearing all caches
* Disabling all caching (sped up the admin tool, but didn’t fix the problem. Re-enabled caching.)
* Disabling the VaultPress plugin (re-eneabled)
* Restarting PHP / Nginx
* Upping the memory on PHP (Changed it back)
* Rebooting the server
* Attempted to fix problem by defragmenting the database by running mysql dump and them restoring the production database from that dump. This failed to fix the problem.
We are running Welcome to WordPress 3.3.1 with a number of custom and non-custom plugins, including:
BWP Google XML Sitemaps
Event Espresso – Calendar
Event Espresso – Members Addon
Event Espresso – SSL/HTTPS
Google Analytics for WordPress
Gravity Forms User Registration Add-On
Make Your Site Social
nginx Compatibility (PHP5)

Any help would be much appreciated. This is killing us.
