Title: Plugin crashed after adding the Google API OAuth details Last modified: February 21, 2018 --- # Plugin crashed after adding the Google API OAuth details * Resolved [towerss](https://wordpress.org/support/users/towerss/) * (@towerss) * [8 years, 3 months ago](https://wordpress.org/support/topic/plugin-crashed-after-adding-the-google-api-oauth-details/) * Hi guys, * I hope you can help me with this one. I have one live site which used the WP Mail SMTP plugin with no issues. I have it configured to send messages to Gmail via SMTP. * I tried to do the same with another site under the same WordPress multisite installation and it did not work. So, I decided to try to use the Gmail API configuration following this guide: [https://wpforms.com/how-to-securely-send-wordpress-emails-using-gmail-smtp/](https://wpforms.com/how-to-securely-send-wordpress-emails-using-gmail-smtp/) * After I clicked the Allow orange button, I proceeded to send a test email. It did not work. It is taking me to this [https://drive.google.com/open?id=1K1c4T58oCvWxIEpp5jwyp4H9GHkhiq1k](https://drive.google.com/open?id=1K1c4T58oCvWxIEpp5jwyp4H9GHkhiq1k) white screen and nothing else happens. * I tried to select other configuration to go back to SMTP, but all the options for other Email methods disappeared: [https://drive.google.com/open?id=1sy-d0dDH30bD56AVo-FVm8kFEth9RdoF](https://drive.google.com/open?id=1sy-d0dDH30bD56AVo-FVm8kFEth9RdoF) * And I cannot change the details og the Gmail option anymore. There is no save, or update, or reset button: [https://drive.google.com/open?id=1devcgwCTLff4kCzwrfj3tqbh5ax62A3t](https://drive.google.com/open?id=1devcgwCTLff4kCzwrfj3tqbh5ax62A3t) * I tried uninstalling the WP Mail SMTP plugin and reinstalling it, but the wrong configuration remains. As I said before, it is just in this site, the other site using the pluggin under the same multisite installation is working fine. * Any help will be really appreciated. * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fplugin-crashed-after-adding-the-google-api-oauth-details%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 3 replies - 1 through 3 (of 3 total) * Plugin Author [Slava Abakumov](https://wordpress.org/support/users/slaffik/) * (@slaffik) * [8 years, 3 months ago](https://wordpress.org/support/topic/plugin-crashed-after-adding-the-google-api-oauth-details/#post-9999718) * Hi * Please check your PHP error log (or enable debug log in WP and try again).
