Hi there,
I have been using this plugin for a long time (Gmail with SMTP). A week ago, I noticed that emails from another forms plugin were not sent. Then, I tried the build-in Gmail API service. I accurately followed all the steps of the guide in order to setup the API. Unfortunately, the following message is now pinned on the top of my wp admin area:
There was a problem while retrieving Auth for gmail: Could not json decode the token
I repeated the whole process several times, even creating different projects, but I was not able to fix the problem. Besides, the plugin “General” tab is getting super slow unless I switch off my Gmail connection on the plugin settings. I cannot send a test email too, a critical error appears when I try it (“There was a critical error on your website. Please check your site administrator email inbox for instructions”).
Plugin version: 2.1.1
WP version: 5.4.2
PHP version: 7.2.26
Any ideas?
Thanks in advance.
