Hello Ernest, thank you for the quick reply.
Firstly apologies it is regarding update from 4.23.3 to 4.24.2, so not a problem with 4.23.3
We have looked into this but we have not found a solution.
Also we have another wordpress staging environment running on the same server with the old plugin version that does not result in an error. The network analysis also returns a 500 server error, but only for the updated plugin version. It times out after about 6-7 seconds.
I have notice the picklist on the frontend has a different html structure now after the update. the hidden label is missing.
Please see the attached screenshots.
Thank you for your support,
Marcel
