Recently, we’ve seen an increase in the number of support requests regarding a plugin upload/update error that is received when uploading or updating UltimateWoo via the WordPress dashboard. The error is as follows:
Could not copy file. ultimatewoo-pro/modules/amazon-s3-storage/amazon_sdk/lib/cachecore/_sql/mysql.sql
As you can see, this error relates to the Amazon S3 module. It is specific for WP Engine users only – all reported cases have been WP Engine users. We have contacted WP Engine’s support, and are awaiting a response. When we hear back, we will update this post. In the meantime, we suggest trying to upload UltimateWoo using (S)FTP. If that still does not work, you should contact WP Engine’s support to have them assist.
We apologize for the inconvenience, and we hope to have this resolves as soon as possible.
