Doesn’t update fields

Hej,

Yesterday I build a welcome dashboard for one of my clients with the plugins:
ACF Frontend form, White label CMS and Dashboard Welcome for elementor. In this dashboard I used ACF frontend form to create buttons and forms to adjust specific posts. And it worked perfectly. But since this afternoon (European time) it does not work anymore. When I click on the button, the form pops up (modal). There I have done my adjustments of tekst en klicked the update button. It goes back to the dashboard, but the changes I made are not update in the posts. I also not getting the message the update wass succesvol (Yesterday I got this message every time I klicked the update button.

Between yesterday and this afternoon I didn’t change anything in related pages and I didn’t install or update plugins. It just stopped working. Please help.

With Kind regards,

Paul Hendriks
