I am sorry for my late reply, but I am too busy last month.
The solution that I have found with author help of course, is to create manually the pum_subscribers table.
I run this in mysql
—————————
CREATE TABLE XXXXXXXXX_pum_subscribers ( ID bigint(20) NOT NULL AUTO_INCREMENT, email_hash varchar(32) NOT NULL, popup_id bigint(20) NOT NULL, user_id bigint(20) NOT NULL, email varchar(191) NOT NULL, name varchar(255) NOT NULL, fname varchar(255) NOT NULL, lname varchar(255) NOT NULL,
(add here a backtick) values (add here a backtick)
longtext NOT NULL, uuid varchar(255) NOT NULL, consent varchar(255) NOT NULL, consent_args longtext NOT NULL, created datetime NOT NULL, PRIMARY KEY (ID), KEY email (email), KEY user_id (user_id), KEY popup_id (popup_id), KEY email_hash (email_hash) ) DEFAULT CHARACTER
SET utf8mb4 COLLATE utf8mb4_unicode_ci
——————————————
The only difference with plugin is the word values needs backticks
and of course change the XXXXXXXXX_pum_subscribers to YOURPREFIX_pum_subscribers
They use a column with name “values” but my database says that it is sql’s reserved word and it needs backtick.
