Classipress: invalid-json error when sending a message to an owner of an ad
Hi
I have
WP 4.6 and CP 3.5.7
I have just realised that when I try to send a messaje to an owner of an ad, in the tab Contact, I get this error: invalid-json, and the message is not sent.
Is this due to the old versions?
Thanks!!
Alvaro
