There are two ways to update W3Speedster: automatic and manual. Remember, if your license has expired, you can renew it on your account page.
This message means there is a limit on the file size you can upload to your site. This limitation may be set at the site level or by your host. The W3Speedster zip file is just over 2MB so if the limit for your site is 2MB or less you would see this error message.
Quick Fix
To resolve it automatically, install the plugin Increase Max Upload Filesize:
https://wordpress.org/plugins/upload-max-file-size/
If that plugin is not able to fix it automatically, you have the following options:
- You can install W3Speedster by uploading it via FTP.
- Contact your host to increase the upload limit.
- Or, if you’re comfortable editing files you can follow the manual steps below to manually increase the upload limit.
Manual Fix
How to increase the upload_max_filesize limit
It’s possible to increase the defined limit by using one of the directives below. Depending on your server setup and host, the method that works could vary from case to case. You don’t have to edit all these files, just find the one that works for your site.
In each example below, “10M” represents a 10MB file size limit. You may set that number as you wish, but be sensible and don’t set it too high.
Make sure you take a backup of your files before editing them!
.htaccess
php.ini file
If your host allows you to modify your site’s configuration with a custom php.ini file, you may use the following:
wp-config.php
functions.php
If you use a child theme, you may add the following to the functions file:
Check your current upload limit
To verify if your attempt to increase the upload limit was successful you can check the current limit.
Go to: Media > Add New
Underneath the upload area, you will see: Maximum upload file size
After implementing one of the above methods, if the limit hasn’t changed it means your host is controlling this and you’ll have to contact them directly.
