Movable Type Knowledge Base: Upload File Too Large

Question

When trying to upload a file, I received an error message saying it was too large. What is the size limit, and can it be changed?

Answer

The default setting for the size of uploaded files is 1MB, to prevent denial-of-service attacks. If you wish to increase this size limit, use the CGIMaxUpload setting in mt-config.cgi¹.

For example, to increase the size limit to 1.5MB, use:

CGIMaxUpload 1500000

Remember to uncomment the setting² in mt-config.cgi. Save and transfer the configuration file back to your server in ASCII mode.

¹ In versions prior to 3.2, the configuration file is named mt.cfg.

² To uncomment a setting means to remove the # from the beginning of the line where it appears.
