You would need to navigate to `wp-content/themes/ Divi` and rename the Divi folder to something like `Divi-broke` so that it disables the theme and you can log in. * If you’re not sure how to do this I would suggest contacting your host who many be able to help. * Thread Starter [russbruz](https://wordpress.org/support/users/russbruz/) * (@russbruz) * [6 years, 2 months ago](https://wordpress.org/support/topic/fatal-error-3422/#post-12488213) * Thanks for the reply! * I renamed the theme as suggested and got this error message when I try to login to the admin: * Warning: strpos(): Empty needle in /homepages/38/d739335324/htdocs/wfmc/wp-content/ plugins/bloom/core/functions.php on line 647 * Warning: Cannot modify header information – headers already sent by (output started at /homepages/38/d739335324/htdocs/wfmc/wp-content/plugins/bloom/core/functions. php:647) in /homepages/38/d739335324/htdocs/wfmc/wp-includes/pluggable.php on line 1265 * Warning: Cannot modify header information – headers already sent by (output started at /homepages/38/d739335324/htdocs/wfmc/wp-content/plugins/bloom/core/functions. php:647) in /homepages/38/d739335324/htdocs/wfmc/wp-includes/pluggable.php on line 1268 * [Howdy_McGee](https://wordpress.org/support/users/howdy_mcgee/) * (@howdy_mcgee) * [6 years, 2 months ago](https://wordpress.org/support/topic/fatal-error-3422/#post-12488341) * You would need to rename plugins too ( or that specific plugin ) so that it’s not active when you log in. It’s possible that the plugin needs an active theme to function correctly and without one ( since you’ve renamed the active Divi theme ) it errors out. * Thread Starter [russbruz](https://wordpress.org/support/users/russbruz/) * (@russbruz) * [6 years, 2 months ago](https://wordpress.org/support/topic/fatal-error-3422/#post-12488352) * Thanks, * Ok did that, now I have a blank screen. but no access to the admin. * [Howdy_McGee](https://wordpress.org/support/users/howdy_mcgee/) * (@howdy_mcgee) * [6 years, 2 months ago](https://wordpress.org/support/topic/fatal-error-3422/#post-12488366) * It sounds like your site has all kinds of issues that span plugins and themes. You would need to enable debugging in your WP Config file to see why you’re getting a blank page: * > [Debugging in WordPress](https://wordpress.org/support/article/debugging-in-wordpress/) * Maybe contacting your host to see if they have suggestions as it could be a PHP version issue since you’re running into multiple problems. It also may not be a bad idea to checkout your local [WordPress Meetup](https://www.meetup.com/pro/wordpress) or [WordCamp](https://central.wordcamp.org/schedule/).
