I tested the woo-commerce header issue locally and it worked fine, while it doesn’t work on your site although I made edits to the same file. Please provide FTP credentials to springboardps.com so that I can troubleshoot the issue further.
Did you customize any thing in this circle flip or woocommerce installation ?
For the text slider interval, I increase it to be 10 seconds. to edit this you need to edit 2 files
you’ll find 10000 at the end of the file, this represents 10 seconds.
you’ll find 10000 here as well, edit this.
Hope this helps.
