http://localhost/phpmyadmin/ shows blank page

I have a problem with the configuration of phpmyadmin.

http://localhost/phpmyadmin/ first gave this error message:

Forbidden

You don't have permission to access this resource.

After this I had configured it to consult the index.php at this address as well: https://i.ibb.co/M7yTF28/Screenshot-2021-03-21-11-41-01.png

Then, because it only showed the code, I would have made an adjustment, after which it now only shows an empty page.

I added this to the current httpd config file:

Code:
<IfModule mime_module>
    AddType application/x-httpd-php .php
    AddType application/x-httpd-php-source .phps
    <FilesMatch "\.php$">
    SetHandler application/x-httpd-php
    </FilesMatch>
    <FilesMatch "\.phps$">
    SetHandler application/x-httpd-php-source
    </FilesMatch>
</IfModule>

Alias /phpmyadmin/ "/usr/local/www/phpMyAdmin/"

<Directory "/usr/local/www/phpMyAdmin/">
Options None
AllowOverride Limit
Require local
Require host localhost
</Directory>

This is my httpd-error.log:

I use php80, mysql57, apache2.4 and phpMyAdmin5-php80.
 
Have you installed www/mod_php80?

As a general rule, you should proceed (if it isn't already the case) step by step. Apache can display a simple html page? If yes, write the most simple php page (index.php) and test it.
<?php phpinfo(); ?>

And if it works, you can try phpmyadmin. Do you have installed it with the port or pkg system?
 
I switched back to PHP 74 because otherwise Adminder would no longer be compatible.
mod_php74 did not solve the issue.
The PHP info page and Adminer both work well. Another thing I have noticed is that when the blank page of phpMyAdmin appears, I can see the correct code of the page when I click on 'View Page Source'.
 
Code:
Alias /phpmyadmin/ "/usr/local/www/phpMyAdmin/" 
<Directory "/usr/local/www/phpMyAdmin/">
Don't put slashes at the end of the directories here. If you add slashes you must open it with http://<myserver>/phpmyadmin/. Without the slashes this works too http://<myserver>/phpmyadmin.
Code:
Alias /phpmyadmin "/usr/local/www/phpMyAdmin" 
<Directory "/usr/local/www/phpMyAdmin">

And add a DirectoryIndex to include index.php, it's looking for index.html by default, which doesn't exist. So it falls back to directory browsing, which is disabled by default, hence the "Forbidden".

 
mod_phpXx is mandatory if you want to use php with Apache (well, almost).

It's probably an error with php (and, by chance, just a php extension missing). You can change the setting in php.ini to make this error appear on the page.

Also, you didn't answer, but phpmyadmin exists both in the port and packages collection. If you install it with one of these means, most of the dependencies will be pulled on your machine.
