Hello! I checked your form at https://arfm.org/donate. What I’m seeing is that the Siteground Optimizer plugin is compressing and combining JavaScript. GiveWP needs some exclusions in that plugin’s settings. I recorded a short screencast of me looking into this: https://www.loom.com/share/14ee09b3e7d144b59914d842a89de28e
What I’d like you to test is temporarily disable the Siteground Optimizer, clear any cache, and see if the form works as expected.
If it works: you’ll need to exclude some common GiveWP JavaScript files from the Siteground Optimizer plugin’s settings:
give.js
give-donation-summary.js
You may or may not have the following in your site:
give-ffm-frontend.js
give-tributes-common.min.js
give-fee-recovery-public.min.js
give-recurring.min.js
Let me know once you’ve implemented and tested the above. I’m here for any further questions or additional assistance. Have a good day!
