I’m having problems with what I think are conflicting plugins. I’ve done my research and I’m a bit stuck.
This conflict only seems to happen a little while after a core or a plugin update. Not immediately, but often around 12 hours later.
What happens is the backend stops responding, whilst the front end appears to work, thanks to the cache. If I disable and then re-enable the plugins (via the db) the site responds again and remains stable until the next update.
So, do you have any ideas how I can diagnose what’s causing this? Or are there any known conflicts in this list?
The site has these plugins and uses a modified Thematic theme
- Akismet
- BackWPup
- Custom Post Widget
- Display widgets
- Google Analytics Dashboard
- Google Analytics graph integration.
- Gravity Forms
- Maintenance Mode
- NextGEN Gallery
- PHP Snippets
- qTranslate
- TinyMCE Advanced
- WordPress Ken Burns Slideshow
- WP Remote
- WP Super Cache
Thanks in advance
Pete

Does your file-server have an error log in the WP Directory? I would start by turning on the DeBug and error reporting via the wp-config file. Open your wp-config and add this from the WordPress Codex Debugging page if it’s not already there:
// Enable WP_DEBUG mode
define('WP_DEBUG', true);
// Enable Debug logging to the /wp-content/debug.log file
define('WP_DEBUG_LOG', true);
// Disable display of errors and warnings
define('WP_DEBUG_DISPLAY', false);
@ini_set('display_errors',0);
// Use dev versions of core JS and CSS file
define('SCRIPT_DEBUG', true);
It should generate an error log and a debug log that may help locate the issue. It sounds like it takes a while for the issue to show up so disabling plugins one at a time might be a long solution. I’d start with the Maintenance Mode, and the BackWPup plugins and go from there.
