Hi folks,
after upgrading from PHP5.6 to PHP 7.3 the chat widget is not working.
It appears and when I try to enter name and message the text field greys out and that's it.
No message is sent.
I updated LiveHelper Chat to the latest version, cleared the Cache but it still does not work.
Any hints?
Thank you.

Hi,
See cache/default.log for an error message. LHC itself works with 7.3php version. So it means it's something with your server.

Thank you remdex ( I am not sure if a message I just posted went through)
I checked cahce/default.log and found this: (which, unfortunately, is totally incomprehensible to me)
