Title: Plugin causing 500 errors Last modified: October 5, 2021 --- # Plugin causing 500 errors * Resolved [macadk](https://wordpress.org/support/users/macadk/) * (@macadk) * [4 years, 7 months ago](https://wordpress.org/support/topic/plugin-causing-500-errors-2/) * Six days ago there was an update to the PublishPress Series plugin. Following that update, I started to have 500 errors appearing on some posts, notably those that are included in a series. * I went through troubleshooting my site, and I think I have localized the problem to this plugin. Any assistance you can offer me in troubleshooting the problem is appreciated. * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fplugin-causing-500-errors-2%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 15 replies - 1 through 15 (of 16 total) 1 [2](https://wordpress.org/support/topic/plugin-causing-500-errors-2/page/2/?output_format=md) [→](https://wordpress.org/support/topic/plugin-causing-500-errors-2/page/2/?output_format=md) * Plugin Author [Steve Burge](https://wordpress.org/support/users/stevejburge/) * (@stevejburge) * [4 years, 7 months ago](https://wordpress.org/support/topic/plugin-causing-500-errors-2/#post-14940865) * Hi [@macadk](https://wordpress.org/support/users/macadk/) * Thanks for using PublishPress Series. * We have limited ability to troubleshoot sites for users here on WordPress.org, but please let us know if you find a bug. * You can go through normal WordPress debugging steps such as disabling other plugins, looking for error messages, or rolling back to an earlier version: [https://wordpress.org/plugins/wp-rollback/](https://wordpress.org/plugins/wp-rollback/) * Plugin Author [Steve Burge](https://wordpress.org/support/users/stevejburge/) * (@stevejburge) * [4 years, 7 months ago](https://wordpress.org/support/topic/plugin-causing-500-errors-2/#post-14962900) * Closing after a week with no replies.

It appears that I am left with no option but to find another solution as it seems you can’t or won’t do more through this forum. I’m very disappointed as I’ve been using your plugin for more than five years. * Plugin Author [Steve Burge](https://wordpress.org/support/users/stevejburge/) * (@stevejburge) * [4 years, 7 months ago](https://wordpress.org/support/topic/plugin-causing-500-errors-2/#post-14970238) * Hi [@macadk](https://wordpress.org/support/users/macadk/) * What does the usual troubleshooting look like, please: * – Disabling other plugins and themes? – Checking the error log? – Rolling back to an earlier version of PublishPress Series? * Thread Starter [macadk](https://wordpress.org/support/users/macadk/) * (@macadk) * [4 years, 7 months ago](https://wordpress.org/support/topic/plugin-causing-500-errors-2/#post-14970647) * Hi Steve, I started with disabling all plugins, then systematically re-enabling them until the 500 errors started to occur – that happened when I re-enabled the Series plugin. At that point, I did not have any caching plugins enabled, but I do use WordFence, and that was enabled. * I followed your suggestion to install WP Rollback. I reverted the Series plugin to the previous version and still had 500 errors. I can enable all the other plugins that I use and have the site work properly, but as soon as I enable the Series plugin the site starts throwing 500 errors. * I did not check any error logs. * I’m happy to give you backend access if you want to have a look. - This reply was modified 4 years, 7 months ago by [macadk](https://wordpress.org/support/users/macadk/). * Plugin Author [Steve Burge](https://wordpress.org/support/users/stevejburge/) * (@stevejburge) * [4 years, 7 months ago](https://wordpress.org/support/topic/plugin-causing-500-errors-2/#post-14970672) * Hi [@macadk](https://wordpress.org/support/users/macadk/) * Thanks for this. We have limited ability to troubleshoot sites for Free users here on WordPress.org. * I would recommend: – Roll back a couple more versions. Is there a point where this problem starts? – Check your error logs. * Thread Starter [macadk](https://wordpress.org/support/users/macadk/) * (@macadk) * [4 years, 7 months ago](https://wordpress.org/support/topic/plugin-causing-500-errors-2/#post-14971044) * Hi Steve, OK, I’ll do that and see what happens, then update this thread. When you are talking about error logs, I’m assuming you’re just talking about PHP errors and not any others, is that correct? Should I be reviewing the Apache logs as well? * Plugin Author [Steve Burge](https://wordpress.org/support/users/stevejburge/) * (@stevejburge) * [4 years, 7 months ago](https://wordpress.org/support/topic/plugin-causing-500-errors-2/#post-14971493) * Hi [@macadk](https://wordpress.org/support/users/macadk/) * You’re looking for any error that can help point towards the cause of this. The PHP logs are the most likely place you’ll find that. * Thread Starter [macadk](https://wordpress.org/support/users/macadk/) * (@macadk) * [4 years, 7 months ago](https://wordpress.org/support/topic/plugin-causing-500-errors-2/#post-14985288) * Hi Steve, * It appeared as if PHP was running out of memory. I’ve increased the maximum memory allocation for PHP to 2048M, and it seems to be running ok at the moment. I’m going to allow the site to run for a few days before I’m confident that things are stable. If problems recur, I’ll come back into this thread. * Thanks, Doug * Plugin Author [Steve Burge](https://wordpress.org/support/users/stevejburge/) * (@stevejburge) * [4 years, 7 months ago](https://wordpress.org/support/topic/plugin-causing-500-errors-2/#post-14985786) * That’s great to hear, thanks Doug. * If you have a second, please leave a positive review to keep the plugin growing: [https://wordpress.org/support/plugin/organize-series/reviews/](https://wordpress.org/support/plugin/organize-series/reviews/) * Thread Starter [macadk](https://wordpress.org/support/users/macadk/) * (@macadk) * [4 years, 7 months ago](https://wordpress.org/support/topic/plugin-causing-500-errors-2/#post-14988863) * Hi Steve, * Well, that didn’t last. My site just won’t run with Series active. What can I do to get more help from you? Do I need to upgrade to a paid version of the plugin? * Plugin Author [Steve Burge](https://wordpress.org/support/users/stevejburge/) * (@stevejburge) * [4 years, 7 months ago](https://wordpress.org/support/topic/plugin-causing-500-errors-2/#post-14990219) * Hi [@macadk](https://wordpress.org/support/users/macadk/) * You do get a lot more support with the Pro version. * With the Free version, we ask users to take the lead in debugging issues. * With the Pro version, our team can do that for you. * Thread Starter [macadk](https://wordpress.org/support/users/macadk/) * (@macadk) * [4 years, 7 months ago](https://wordpress.org/support/topic/plugin-causing-500-errors-2/#post-15004376) * Steve, * In the process of trying to troubleshoot the series plugin problem, it appears that the taxonomy has been broken, so although I have series defined and posts assigned to the series, it is now impossible to get to the page for a series. Clicking on a series in the sidebar widget throws a 404 for the series page. I think I created this problem by deleting the plugin and reinstalling it. * Any thoughts? - This reply was modified 4 years, 7 months ago by [macadk](https://wordpress.org/support/users/macadk/). * Thread Starter [macadk](https://wordpress.org/support/users/macadk/) * (@macadk) * [4 years, 6 months ago](https://wordpress.org/support/topic/plugin-causing-500-errors-2/#post-15040447) * So I’ve paid for a premium version of the plugin, and I’ve now tried twice to open a support ticket, and neither ticket is showing on my account. I really need support with this problem. * Please tell me how I can get support with the issue I’m having. * Plugin Author [Steve Burge](https://wordpress.org/support/users/stevejburge/) * (@stevejburge) * [4 years, 6 months ago](https://wordpress.org/support/topic/plugin-causing-500-errors-2/#post-15040508) * Hi [@macadk](https://wordpress.org/support/users/macadk/) * We’ve got your support ticket and replied a few minutes ago.
