Urgent

Hi

This is Angelos / website https://miscplus.gr/?page_id=5078

Volunteers Form.  Some days I have successful submitions and some days I get messages from people that when they fill the form they get a NO MESSAGE in RED

so I go to wordpress and try to figure out and without doing anything just export the list to have a copy then is working again

Any ideas

is getting frustrating that I have to fill the form myself every day to check if its working
