If you cannot get into admin to remove/change it, FTP into the wp-content/themes/ directory and rename ‘education’ to something else. This will deactivate the theme. * Thread Starter [akramisb87](https://wordpress.org/support/users/akramisb87/) * (@akramisb87) * [10 years, 4 months ago](https://wordpress.org/support/topic/php-fatal-error-70/#post-7000361) * Mike Jolley I have change name but no difference in site.

Admin panel is working properly. * Plugin Contributor [Mike Jolley](https://wordpress.org/support/users/mikejolley/) * (@mikejolley) * [10 years, 4 months ago](https://wordpress.org/support/topic/php-fatal-error-70/#post-7000362) * Are there any other themes installed in wp-content/themes/? * Thread Starter [akramisb87](https://wordpress.org/support/users/akramisb87/) * (@akramisb87) * [10 years, 4 months ago](https://wordpress.org/support/topic/php-fatal-error-70/#post-7000364) * Yes,but these are only wordpress themes. * Plugin Contributor [Mike Jolley](https://wordpress.org/support/users/mikejolley/) * (@mikejolley) * [10 years, 4 months ago](https://wordpress.org/support/topic/php-fatal-error-70/#post-7000366) * Remove it then. You won’t be able to access admin whilst your theme is causing fatal errors.
