So we can determine more on this, please share the following: 1. Your Site Health information. [_(Tools > Site Health > info > Copy site info to clipboard)_](https://i.imgur.com/Rtkmsba.png) 2. Have you made any recent changes to your WordPress environment, such as changing the location of your WordPress files? * Note also that you may also be able to manually upload and install the module related plugins from Performance Lab, as zip files. For example you may wish to download the Modern Image formats plugin (v2.0.1) [from here](https://downloads.wordpress.org/plugin/webp-uploads.2.0.1.zip). After doing so, please check does this install as expected. * Let me know if you have any questions with the above. * Plugin Author [Weston Ruter](https://wordpress.org/support/users/westonruter/) * (@westonruter) * [1 year, 11 months ago](https://wordpress.org/support/topic/plugin-not-found-9/#post-17833619) * For reference, see the [code location](https://github.com/WordPress/performance/blob/2b2bebcb9a6285fac8653d078c1d49588f3c6b70/plugins/performance-lab/includes/admin/plugins.php#L277-L279) for this error message. Specifically, this code seems to be failing: * ```wp-block-code $plugins = get_plugins( '/' . $plugin_slug ); ``` * I wonder if there is a custom directory being used for installed plugins? * Lastly, instead of installing the plugins from ZIP files you can also just search the plugin directory for the plugin and install it that way instead. * [gordonrjones](https://wordpress.org/support/users/gordonrjones/) * (@gordonrjones) * [1 year, 6 months ago](https://wordpress.org/support/topic/plugin-not-found-9/#post-18130597) * i’m experiencing the same issue with the Performance Lab plugin. installed via the directory and manual methods – same result. error screenshot: [https://www.awesomescreenshot.com/image/51530496?key=4a2d4576e6eeb46a2d4a159a81ccad0f](https://www.awesomescreenshot.com/image/51530496?key=4a2d4576e6eeb46a2d4a159a81ccad0f) no custom plugin directory or other shenanigans.any ideas? * Plugin Author [Weston Ruter](https://wordpress.org/support/users/westonruter/) * (@westonruter) * [1 year, 6 months ago](https://wordpress.org/support/topic/plugin-not-found-9/#post-18130638) * [@gordonrjones](https://wordpress.org/support/users/gordonrjones/) There are three possible locations where this error could be coming from: 1.

[https://github.com/WordPress/performance/blob/7c6aa818b5c9707d7619a91614548ef51efba033/plugins/performance-lab/includes/admin/plugins.php#L363](https://github.com/WordPress/performance/blob/7c6aa818b5c9707d7619a91614548ef51efba033/plugins/performance-lab/includes/admin/plugins.php#L363) * All three are in that same file: `includes/admin/plugins.php`. Unfortunately we’re reusing the same string for each error. Are you comfortable editing the strings in the plugin file editor in WordPress to, for example, add `__LINE__` after the strings so we can differentiate between them? This will help us debug where the error is coming from. * Aside: I also see that we’re using the string with the `default` text domain once, but with the `performance-lab` text domain twice. That’s not good either. I’ll open a PR to fix this for the next release, as well as to make the strings unique. * Plugin Author [Weston Ruter](https://wordpress.org/support/users/westonruter/) * (@westonruter) * [1 year, 6 months ago](https://wordpress.org/support/topic/plugin-not-found-9/#post-18130660) * PR for improving the translation strings: [https://github.com/WordPress/performance/pull/1651](https://github.com/WordPress/performance/pull/1651) - This reply was modified 1 year, 6 months ago by [Weston Ruter](https://wordpress.org/support/users/westonruter/). * [gordonrjones](https://wordpress.org/support/users/gordonrjones/) * (@gordonrjones) * [1 year, 6 months ago](https://wordpress.org/support/topic/plugin-not-found-9/#post-18133728) * thanks Weston – i’m dumb/brave enough to hack at the php, but will definitely some very prescriptive instructions 😉 * Plugin Author [Weston Ruter](https://wordpress.org/support/users/westonruter/) * (@westonruter) * [1 year, 6 months ago](https://wordpress.org/support/topic/plugin-not-found-9/#post-18133752) * [@gordonrjones](https://wordpress.org/support/users/gordonrjones/) Here’s one better for you. You can install the `performance-lab.zip` linked to from the [PR comment](https://github.com/WordPress/performance/pull/1651#issuecomment-2475026928) I just left. That includes the updated strings, so we’ll be able to narrow-down where the error is coming from. * [gordonrjones](https://wordpress.org/support/users/gordonrjones/) * (@gordonrjones) * [1 year, 6 months ago](https://wordpress.org/support/topic/plugin-not-found-9/#post-18133893) * thanks! installed (3.6.0-alpha) and activated. from “settings” this is there error: [https://www.awesomescreenshot.com/image/51553919?key=8c33abeb9c9a34877d2d3755c6229e6d](https://www.awesomescreenshot.com/image/51553919?key=8c33abeb9c9a34877d2d3755c6229e6d) * Plugin Author [Weston Ruter](https://wordpress.org/support/users/westonruter/) * (@westonruter) * [1 year, 6 months ago](https://wordpress.org/support/topic/plugin-not-found-9/#post-18133945) * Well, it seems that the API request is not returning the expected plugins. * This is the PHP code that seems to not be returning the expected data: [https://github.com/WordPress/performance/blob/762df7464d293ec7dcd46ad19d0e6ceb5f81fcb9/plugins/performance-lab/includes/admin/plugins.php#L36-L56](https://github.com/WordPress/performance/blob/762df7464d293ec7dcd46ad19d0e6ceb5f81fcb9/plugins/performance-lab/includes/admin/plugins.php#L36-L56) * I don’t suppose you could find a way to run that PHP code on your site and do a `var_dump()` to see what it contains? * [gordonrjones](https://wordpress.org/support/users/gordonrjones/) * (@gordonrjones) * [1 year, 6 months ago](https://wordpress.org/support/topic/plugin-not-found-9/#post-18153094) * that’s getting a bit above my comfort/knowledge level – sorry. i will probably de-activate and wait for the next version to see if that somehow fixes. thanks for the assistance. * Plugin Author [Weston Ruter](https://wordpress.org/support/users/westonruter/) * (@westonruter) * [1 year, 6 months ago](https://wordpress.org/support/topic/plugin-not-found-9/#post-18153095) * In any case, you don’t need to install the plugins via the Performance screen. You can install them directly.

Strange. I wonder if there is an issue with how WPEngine is configuring their plugin directory lookups. In any case, you have all the plugins installed and active, apparently, so you don’t need to activate the features from the Performance screen.
