Plugin activation error.(nginx error500)
The existing site is in normal use.
But after installing new site,
At first, the plug-in was installed normally.
One day later, while logging in to the admin page, the error message “Error 500” was printed.
I was able to recover after changing the plug-in name after FTP connection.
Based on WordPress 5.3.1 (nginx+php7.2).
If the plug-in is deleted and reinstalled, the same “error 500” message is printed.
Although debug mode of wp-config.php is enabled, no message is output.
I have left information to access the admin page below.
Data is a real-world site and should not be initialized.
