 * I just installed version 4.0 and the plugin is unable to authenticate itself 
   on Google.
 * This is the log:
 * February 25, 2020 6:11:34 PM PHP 7.2.24-0ubuntu0.18.04.3Array

 * How can I recover the old version of the plugin, especially version 3.0?

 * Hi [@srobodao](https://wordpress.org/support/users/srobodao/),
 * It seems you would have used the same authentication key multiple times for the
   integration.
 * Can you get the fresh key and then try out.
 * Also, the old version will not work now as it has Google API V3 version and it
   has been now shutdown.
 * Thanks
    Abdullah

 * Thanks for your answer.
 * Tried again, and now “white page” when view debug log; is it ok? if white page
   is ok, form is not sending data to Google Sheet.
 * Thanks in advance.

 * Yes, means no errors, now entry must be shown in google sheet.
    If still not,
   please refer this quick video and make sure you have entered sheetname, sheetid,
   tabname and tabid
