Error related to max post size, upload max file size, max execution time, max input time or memory limit

If you get one of the errors below during a request:

• PostTooLargeException in ValidatePostSize.php line XX:

• HTTP 500 Payload Too Large

• Unable to decode input (e.g. during Image upload)

• or any other error related to size, time or memory limit

You have to check the following parameters in your php.ini file:

• max_file_size

• upload_max_filesize

• post_max_size

You will have this issue on several occasions and it's usually because the (default) max_file_size value is small than the size of the file you try to upload.

Solution:

If you facing the issue above, as well as the file size limit, there is also a memory limit to consider. Several variables (from your php.ini file) need consideration…

post_max_size
upload_max_filesize
max_execution_time
max_input_time
memory_limit

Exemple:

This configuration can allow you to upload 17MB file

post_max_size = 128M
upload_max_filesize = 64M
max_execution_time = 120
max_input_time = 240
memory_limit = 512M

Done.

Advanced Solutions (Rarely Used):

If the solution above doesn't solve the issue (that is very rare), you need to consider the settings below:

• Nginx Settings
  Even without knowing how to configure it, you need to care about one setting in nginx.conf file: client_max_body_size. Here’s the official documentation.
  As you can read, default value is only 1m, which means that your whole POST request may be maximum 1MB. So you need to change that setting to 20m or higher.

• Apache Settings
  If you’re using Apache web-server, there’s also a setting for that called LimitRequestBody. Here’s the official documentation. The difference here is that Apache doesn’t give any restrictions by default. So there’s a chance that you will never need to edit this value, but just in case, it’s good to know it exists.
