Update failed while updating & installing plugins in WordPress

I faced this error while trying to install a new plugin (Wordfence):

Update failed. Installation failed: -1.

Error while attempting to install Wordfence.

Later faced the same Update failed error while trying to update my plugins.

I think it happened after deleting the Admin Menu Editor plugin.

Additional info: I am using WordPress 6.1.1; I have FileZilla; My hosting server Eternalhost.net uses ISPManager.

Googled this and found some results (even in Stack Overflow). Tried changing wp-content/upgrade folder permission to 644, 755, and 777. No result.

Tried inserting this Define(‘WP_TEMP_DIR’, ABSPATH . ‘wp-content/’); code inside wp-config.php file. No progress.

Tried restoring to my previous backup with UpdraftPlus where everything worked fine and had Admin Menu Editor plugin. Still no luck.

    Thanks, mate. It worked. The problem was exactly as you said. They have updated the plugin, and I can see this message in the changelog:

    v3.1.26 – 22-February-2023 – Fix: Plugin installation from WordPress plugins dashboard fails when Starter Template is activated.

    Lucky me.

    Got exactly the same problem on many of my WordPress instances. For me, it was a plugin that interfered with installation and updating on the sites.

    Faulty Plugin: Starter Templates

    I just found that they mentioned this problem in their release notes. If you have this plugin installed: Deactivate it and run all updates incl. the faulty one itself. That should do the trick.

    Happened to me too. It’s the Starter Template plugin. Disabled the starter template plugin. Problem solved. Every plugins were updated.
