Title: “Debug Information” tab empty Last modified: February 1, 2019 --- # “Debug Information” tab empty * Resolved [richbhanover](https://wordpress.org/support/users/richbhanover/) * (@richbhanover) * [7 years, 4 months ago](https://wordpress.org/support/topic/debug-information-tab-empty/) * Using WP 4.9.9 and Health Check 1.2.5. I have enjoyed this plugin many times on many sites for collecting information and finding problems. * My problem: The “Site Status” works as expected (info below). But clicking “Debug Information” tab grinds away for 15-30 seconds, but then leaves an empty page.( The other tabs – Troubleshooting, PHP Information, and Tools show the expected content.) * Any idea what might cause this? What additional information could I provide to troubleshoot this? Many thanks. * ``` WordPress Version 4.9.9 - We were unable to check if any new versions are available.

I know the debug tab is a heavy task, collecting a fair amount of data, and is something we should probably investigate moving forward if there’s some ways to improve the performance there, I’ve created [https://github.com/WordPress/health-check/issues/249](https://github.com/WordPress/health-check/issues/249) to track this. * Thread Starter [richbhanover](https://wordpress.org/support/users/richbhanover/) * (@richbhanover) * [7 years, 4 months ago](https://wordpress.org/support/topic/debug-information-tab-empty/#post-11163126) * Thanks for getting back to me. I was also on an unreliable hosting service, so I have switched to a new server. * From the user standpoint, the blank page is scary. (“Yikes! Has my computer stopped? Is my site dead?”) * Maybe there’s a way to post a “Collecting a fair amount of data…” message initially, then update when the server has results? (That would leave the “collecting…” message there to give a better support message.) * Best regards * Rich Viewing 3 replies - 1 through 3 (of 3 total) The topic ‘“Debug Information” tab empty’ is closed to new replies. * ![](https://ps.w.org/health-check/assets/icon.svg?rev=1828244) * [Health Check & Troubleshooting](https://wordpress.org/plugins/health-check/) * [Frequently Asked Questions](https://wordpress.org/plugins/health-check/#faq) * [Support Threads](https://wordpress.org/support/plugin/health-check/) * [Active Topics](https://wordpress.org/support/plugin/health-check/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/health-check/unresolved/) * [Reviews](https://wordpress.org/support/plugin/health-check/reviews/) * 3 replies * 2 participants * Last reply from: [richbhanover](https://wordpress.org/support/users/richbhanover/) * Last activity: [7 years, 4 months ago](https://wordpress.org/support/topic/debug-information-tab-empty/#post-11163126) * Status: resolved
