Hello Epi team!

We have just upgraded our TinyMCE, and suddenly the forms we have on our website stopped working (ie.whenever a user submits a form, we receive nothing although everything is correctly configured when it comes to the form).

Our developer witnessed the following error message:

"Event message: Forms authentication failed for the request. Reason: The ticket supplied was invalid." - This error only showed up when trying to navigate to pages with forms.

Is there anything we should modify after the TinyMCE update, as read over the internet, there seems to be something we need to adjust in the website configuration in IIS?

Can you please give us clues what needs to be done?

Kindly advise.

Thanks!
