MailPoet requires write permissions inside the /wp-content/uploads folder

I recently had GoDaddy move a WP site from regular hosting to WP hosting. When I went to upload, I got the following three errors:

MailPoet Error: MailPoet requires write permissions inside the /wp-content/uploads folder. Please read our instructions on how to resolve this issue.

The Page “Calendar” uses the “/calendar” slug: the Events Calendar plugin will show its calendar in place of the page.

Failed to render template “newsletters.html”. Please ensure the template cache folder “/home/*old_user_name*/public_html/wp-content/uploads/mailpoet/cache” exists and has write permissions. Terminated with error: “Unable to create the cache directory (/home/*old_user_name*/public_html/wp-content/uploads/mailpoet/cache/11).”

Here’s what I’ve done so far:
* Checked everything on this help page and several others: https://kb.mailpoet.com/article/152-minimum-requirements-for-mailpoet-3#folder_permissions
* Followed the instructions in the video on the above page
* Checked with GoDaddy that all permissions are correct, PHP is installed, etc.
* Uninstalled and reinstalled MailPoet 2 and MailPoet 3.
* Searched Google, YouTube, and this site for other inquiries

I think the issue lies with the last error in that MailPoet is looking for a directory structure under the previous site. Is there a way to manually change that directory to the new directory structure? Or is there a way to get MailPoet to refresh the settings to point to the current site?

Many, many thanks for any help you can provide!
