The link you followed has expired. Please try again. - Issue uploading Divi Theme

Hey, wondered if someone could help please. I am trying to upload the Divi Theme (8.5mb) and it keeps on coming up with this error message:

"The link you followed has expired.

Please try again."

After reading some forum posts yesterday I have asked the hosting company to set the following values in the “ini.php” file:

post_max_size 128M
max_execution_time 180
upload_max_filesize 256M
max_input_time 600
max_input_vars 5000

I have then tried to upload the theme again via Wordpress and it still comes with the same error message.

Could someone give me some guidance on this please? Where do I go from here?

Thanks in advance
