Hi, @philipg100.
Glad you reached out. I can help you fix this error. If you have the Form Field Manager add-on installed on your site, here is what happened.
We released a new version of GiveWP and Form Field Manager that fixes the issue you are facing (GiveWP 2.29.0 and Form Field Manager 2.1.0).
First, if your site is broken, I would restore a backup of your site so you are up and running again.
Then, I’d deactivate the Form Field Manager add-on, update GiveWP, update the Form Field Manager add-on, and then activate it again.
To fix it, you need to update both GiveWP and the Form Field Manager add-on. In this case, you can click on Plugins > Installed Plugins and click to update your plugins. If you do not see an update for it, it’s just the cache. You can navigate to Dashboard > Updates and click on Check Again. It will check for the updates and clear the cache and you’ll be able to update the plugin.
Before taking any steps for troubleshooting or updating, I highly recommend taking a good backup of the site you can confidently restore from. Having a backup of your site is essential to a solid workflow, and will allow you to restore to a previous version of the site if you run into any issues. You can read more about our top recommendations for taking a backup here:?https://givewp.com/backup-for-faster-troubleshooting/
However, if this is not your case, please send a copy of the error you get when you try to update it and we will help you.
Your success with online donations is our number one priority. Looking forward to helping you get to the bottom of this!
