Installed and got a blank plugins screen

I just noticed that WP generated an email automatically when this problem occurred and thought its contents might help you determine the cause of the anomaly:

Howdy!

Since WordPress 5.2 there is a built-in feature that detects when a plugin or theme causes a fatal error on your site, and notifies you with this automated email.

In this case, WordPress caught an error with one of your plugins, Plugins Manager.

First, visit your website (https://tutormi.ca/) and check for any visible issues. Next, visit the page where the error was caught (https://tutormi.ca/wp-admin/plugins.php?plugin_status=all&paged=1&s) and check for any visible issues.

Please contact your host for assistance with investigating this issue further.

If your site appears broken and you can’t access your dashboard normally, WordPress now has a special “recovery mode”. This lets you safely login to your dashboard and investigate further.

(I’ve erased the link!)

When seeking help with this issue, you may be asked for some of the following information:
WordPress version 5.3.2
Current theme: GeneratePress (version 2.4.1)
Current plugin: Plugins Manager (version 1.1.0)
PHP version 7.2.24-0ubuntu0.18.04.1

Thanks for the feedback. I fixed the error. Upgrade to 1.1.1

Artem,

Well, the plugin no longer creates a blank plugin screen – but I still don’t think it’s working as it should. It obviously adds small icons/illustrations of all of the plugins (nice!), but I understood that there was to be an added link on each active plugin that would both deactivate and delete it at the same time. No such link appears, as you can see: https://i.imgur.com/0w1VCyd.png Here’s another shot of my plugin screen: https://i.imgur.com/qpQ0Ubq.png

I have two other plugins that directly affect how plugins function and the plugins screen: Plugin Notes Plus and WP Rollback. Deactivating both of these doesn’t affect your plugin at all – still no deactivate/delete link shows up! However, the Bulk Actions has such an option, as you can see: https://i.imgur.com/Vzkyf3p.png – so part of your plugin is working!

One other issue: using the search term “plugins manager” at the WP plugins repository doesn’t find your plugin! I need to search on “plugins manager webtemyk” to find it – not very easy!

Happy Christmas!

So here is the same link “Delete” on the screenshot. https://i.imgur.com/qpQ0Ubq.png If you disable my plugin, this link will disappear for activated plugins. In the last update, I shortened the name of the link, as many plugins add their links and they become in two rows.

With searches in the WordPress repository, I can not do anything, most likely the plugin is not yet popular enough.
