Hello @agentrosehq
Nastia was referring to the page where the embed is added, but it’s clear that you can’t save Hustle settings now. This should be happening due to a conflict with another plugin most probably, thus a conflict test is needed to narrow this down.
How to:
First, create a recent backup in case you lose any settings during the test and have to restore to a previous working state.
Then deactivate all plugins apart from Hustle, activate a default theme like TwentyTwenty, clear all caches and check again if the issue is still there. If not, it means that something is conflicting, so start activating the remaining plugins and theme, one by one this time, checking every time for the reported issue, until you reproduce the issue, thus finding the conflicted combination. The following flowchart image can assist you during this test: https://premium.wpmudev.org/wp-content/uploads/2015/09/Support-Process-Support-Process.gif
If this is a live website with traffic, I’d rather advise to create a staging environment, meaning a complete and exact copy of this installation into another location/folder in the same server, using a separate database, and perform the test in there instead without worrying about the live site.
Side question, does Hustle make sure all emails are authentic and if not, what can I do to ensure signup emails are authentic? I have integrated with MailChimp, if that helps – there’s a few more emails in the Hustle widget on WordPress than there are on Mailchimp and both lists started at the same time.
Hustle doesn’t provide such functionality, so you’ll have to rely on the newsletter providers like Mailchimp and techniques like the double opt-in, which can also be the case why you’re having less subscribers in Mailchimp at the moment.
Warm regards,
Dimitris
