WSOD after update from 4.9.57.p to .60.p

After updating from 4.9.57.p to .60 we’re getting a white screen of death. PHP error log remained empty, but a debug sessions shows an InvalidArgumentException in Registry.php on line 391 in the method registerManifestFile().

The provided value for $url_base is not a valid url. The url provided was: /plugins/event-espresso-core-reg/assets/dist/
$manifest_file = “/path/to/website/plugins/event-espresso-core-reg/assets/dist/build-manifest.json”
$namespace = “core”
$url_base = “/plugins/event-espresso-core-reg/assets/dist/”

(The “/wp-content/plugins” folder was moved to “/plugins” years ago; this is not an issue)

We reverted back to .57 and all was well again.

Hi TopOnline,

May I ask can you post a list of the installed plugins on your site? The reason I ask is because normally the first part of the $url_base will include your site’s URL, but that’s not happening on your site, and that’s causing the WSOD.

Thanks for the list, I guess there may be some code in one of those plugins that’s related to this issue with the script URL not validating.

May I ask can you post the code that you’re using that changes plugins_url to not include the wp-content folder in the URL? That may be running too late and may need to be moved to an earlier hook point.

I checked how/where the differing location for plugins was implemented, and found whomever set up this site defined differing WP_PLUGIN_DIR, PLUGINDIR and WP_PLUGIN_URL constants, except the URL constant was not actually an URL, but /plugins.

Changed it to a full URL, upgraded EE again and all worked fine.

Thanks Josh!
