I uninstalled the plugin and I knew at that moment that I have to use MailPoet - Uninstall .
We then executed instructions on the page : http://support.mailpoet.com/knowledgebase/instructions-to-completely-uninstall-wysija/ , but after I reinstalled MailPoet Newsletter Update my warning appears procedure to MailPoet version " 2.0" failed! Table ' yyyyyy_xxxxxxxx_wysija_email ' does not exist ( ALTER TABLE
INT UNSIGNED NOT NULL modified_at DEFAULT '0 ' ;) and the page settings appear many such alerts WordPress database error: [ Table' yyyyy_xxxxxx_wysija_user ' doesn ' t exist ]
SELECT user_id FROM
xxxxxx_wysija_user WHERE keyuser = " bhhs65dvd87dffgufuyu ..... "
Also search function modules admin panel does not work and I get error 404.
Please much they helped me to fix this problem because I want to reinstall this plugin and I would like to give him up .
