Title: Plugin conflict? Last modified: October 30, 2017 --- # Plugin conflict? * Resolved [hommealone](https://wordpress.org/support/users/hommealone/) * (@hommealone) * [8 years, 7 months ago](https://wordpress.org/support/topic/plugin-conflict-177/) * Hi, * We’re using the latest version of WordPress (4.8.2). Our site crashed the other day with a 500 Server Error. We disabled all of our plugins (30+) to restore the site, and did troubleshooting by enabling them one-by-one. Enabling WP Ecommerce again crashed us with the same 500 Server Error. (Disabling WP Ecommerce again and re-enabling crashes the site each time we try.) We were able to re-enable all other plugins except WP Ecommerce. * Short of the even-more-disruptive and time consuming next troubleshooting tests as detailed in this forum’s sticky post, I’m wondering if anyone has run into any _particular _plugin conflicts recently, so I can check if we might have the same ones? * Can I also try uninstalling WP Ecommerce and re-installing a fresh copy, in case we might have a corrupted file? I’m usually able to update WP Ecommerce normally( we haven’t hacked the plugin or anything like that). Would we loose our WP Ecommerce settings or product information or, as I expect, are those stored in the database and not in the plugin files? * Thanks!

Make sure you are on the latest release which is 3.13.1 and no removing and installing again will not remove your products since its all in the database. * Thread Starter [hommealone](https://wordpress.org/support/users/hommealone/) * (@hommealone) * [8 years, 7 months ago](https://wordpress.org/support/topic/plugin-conflict-177/#post-9634752) * Thanks! * At the time of the crash, the logs looked like this; don’t know if there is anything helpful here: * Apache errors: [Fri Oct 27 10:22:20 2017] [error] mod_fcgid: domain=www.domain. org too many /dh/cgi-system/php56.cgi processes, skip the spawn request [Fri Oct 27 10:22:21 2017] [error] mod_fcgid: domain=www.domain.org too many /dh/cgi- system/php56.cgi processes, skip the spawn request [Fri Oct 27 10:22:22 2017][ error] mod_fcgid: domain=www.domain.org too many /dh/cgi-system/php56.cgi processes, skip the spawn request * Domain Error logs: [Fri Oct 27 10:20:35 2017] [error] [client 96.233.194.218] Premature end of script headers: index.php [Fri Oct 27 10:20:45 2017] [error][ client 23.96.219.115] Premature end of script headers: index.php [Fri Oct 27 10:22:51 2017] [error] [client 66.251.58.2] Premature end of script headers: index.php [Fri Oct 27 10:23:35 2017] [error] [client 96.233.194.218] Premature end of script headers: index.php * And thanks for confirming about the re-install. I’ll give that a try, just in case. * [Mihai Joldis](https://wordpress.org/support/users/misulicus/) * (@misulicus) * [8 years, 7 months ago](https://wordpress.org/support/topic/plugin-conflict-177/#post-9634774) * Those look like server related issues and the second one could be related to the first apache errors. * Do this. Enable debug in the wp-config.php file * define(‘WP_DEBUG’, true); define(‘WP_DEBUG_LOG’, true); * And see if you get the website to crash again then check the debug.log file under wp-contents/ * You could also add define(‘WP_DEBUG_DISPLAY’, true) to show any errors on the screen * Thread Starter [hommealone](https://wordpress.org/support/users/hommealone/) * (@hommealone) * [8 years, 7 months ago](https://wordpress.org/support/topic/plugin-conflict-177/#post-9635037) * Thanks for this good suggestion. I will probably not be able to take the site off-line for more testing until next weekend. I’ll try then! Thanks again. * Thread Starter [hommealone](https://wordpress.org/support/users/hommealone/) * (@hommealone) * [8 years, 7 months ago](https://wordpress.org/support/topic/plugin-conflict-177/#post-9653591) * The problem seems to be resolved. I was unable to shut down the website for further troubleshooting till the weekend. By the time that the weekend arrived, I put it in maintenance mode and then re-enabled the plugin (with debugging enabled) expecting another crash; no crash occurred. The store is now working again along with the rest of our site. * Several other plugins that we run had new versions released during the week. I updated all of those before re-enabling WP ecommerce. I’m guessing that a plugin conflict was the problem, and that the conflict might have been resolved with the updates to those other plugins? * Anyway, thank you for your help and suggestions!
