WordPress Error 500 while installing Scalia theme

Solution:1

The file upload size is less. You can increase the file upload size. Two approach either set them in your script like so

<?php

ini_set(‘upload_max_filesize’, ‘<YOUR_VALUE_HERE>M’);

If that does not work which rarely happens try creating your own .htaccess file with a text editor and input the following

php_value post_max_size <YOUR_VALUE_HERE>M

php_value upload_max_filesize <YOUR_VALUE_HERE>M

Hope this fix it!

Solution:2

in your wp-config.php file

1)Increasing the PHP Memory Limit

define(‘WP_MEMORY_LIMIT’, ‘128M’);

2)increase upload file size with value of your file

@ini_set( ‘upload_max_size’ , ’20M’ );

@ini_set( ‘post_max_size’, ’13M’);

3.check .htaceess and files permissions if you have .htaccess rename it with for example .htaccess-old and create new one

4.use default theme then try to reinstall scalia
