502 Error after installing IP Locator and/or Device Detector

Hello,

The Sessions plugin works until I install other PerfOps tools. Specifically trying to add IP Locator and Device Detector. After installing one or both of those plugins, loading the Active Sessions Management page returns a 502 error. Both IP Locator and Device Detector work with/without the Sessions plugin activated.

Looking at the error logs I see this:

PHP Fatal error: Uncaught Error: Class “POSessions\System\Database” not found in /nas/content/live/prep101stg/wp-content/plugins/sessions/includes/features/class-schema.php:201\nStack trace:\n#0 /nas/content/live/prep101stg/wp-content/plugins/sessions/includes/features/class-schema.php(70): POSessions\Plugin\Feature\Schema::purge()\n#1 /nas/content/live/prep101stg/wp-includes/class-wp-hook.php(306): POSessions\Plugin\Feature\Schema::write()\n#2 /nas/content/live/prep101stg/wp-includes/class-wp-hook.php(332): WP_Hook->apply_filters(NULL, Array)\n#3 /nas/content/live/prep101stg/wp-includes/plugin.php(517): WP_Hook->do_action(Array)\n#4 /nas/content/live/prep101stg/wp-includes/load.php(1124): do_action(‘shutdown’)\n#5 [internal function]: shutdown_action_hook()\n#6 {main}\n thrown in /nas/content/live/prep101stg/wp-content/plugins/sessions/includes/features/class-schema.php on line 201, referer: https://prep101stg.wpengine.com/wp-admin/plugins.php?plugin_status=all&paged=1&s

This issue only appears to affect our hosted sites, specifically on WP Engine. I’ve tested on completely separate websites, and I see the same issue. This doesn’t happen on local versions of the same sites, however.

I’ve reached out to WP Engine support, and they sent me back here as it only happens once enabling another PerfOps plugin. Is there anything specific I need to do to get this working on a WP Engine environment? Any insight/help would be appreciated. We’d love to be able to use more than just the Sessions plugin.

Thank you,

Torin
