ZIP file doesn’t work

Hi,

You can also set Chunk Upload option Downloads > Settings > Basic > Upload Settings. However, if it relates to maximum file upload size problem, you can also check this doc too, https://www.wpdownloadmanager.com/how-to-increase-the-maximum-file-upload-size-in-wordpress-download-manager/

Thanks.

I think this is causing for PHP memory setting

Fixing the Error there are a couple of ways on how to go about resolving this error. These include:

1.Editing the wp-config.php file
2.Editing the php.ini file
3.Editing the .htaccess file

1.Editing the wp-config.php file

Here you will need to edit thewp-config.php file.
define( 'WP_MEMORY_LIMIT', '256M' );

2.Editing the php.ini file

On a live install, the file can be accessed within the root of your install, that is within the /public_html/ folder. Note that the file is not installed by WordPress but in most cases set up by your host. If you are using CPanel as your control panel, for example, make sure the checkbox for “Show Hidden Files” is checked and then click Go. You may check into this article on how to go about editing the file. Before editing the file, kindly preserve a backup to it by downloading it to your computer.
Once this is done, open the file, add or edit the following line:

memory_limit 512M

3.Editing the .htaccess file

The .htaccess file is a file located within the root of your WordPress files.

You will need to add or edit the following code to the bottom of the file:

php_value memory_limit 256M

With this done, you can then save your changes and check if the error is resolved.

Thanks.
