Nonce did not verify – Shopengine admin

Try to re-gen your salt, here:
https://api.www.ads-software.com/secret-key/1.1/salt/
and add it in to your wp-config file.

Does the site_home and site_url in your _options database table match your live URL?
Do you have a valid SSL installed, and is the https:// reflected in this table?

I will check, thank you.

I do have an SSL installed and the rest of my site and WordPress and associated plugins work normally. It’s just ShopEngine that is giving me this nonce issue.

Off the top of my head to troubleshoot:
– make sure you have your cache plugin disabled from Siteground, and turn off the cache in your SG control panel
– disable all plugins and enable back on one by one (especially any plugins related to cache, membership, security, Jetpack, reCaptcha)
– try a default WordPress theme like twentytwenty
– ask in the Shopengine forum: https://www.ads-software.com/support/plugin/shopengine/

re-gen of salt did not work.

The issue was a conflict between ShopEngine and Woocommerce Ultimate Gift Card Pro. The developer (Gift Card Pro) solved the issue from their end.
