I am having issues with my wordpress site. I have no access to the online dashboard, so I have been trying to troubleshoot through FTP. I have turned on the debugger in the
wp-config.php file. From the output log I can see that the error is stemming from the theme
best-simple. The error is below:
[12-May-2019 13:37:39 UTC] PHP Warning: Cannot modify header information - headers already sent by (output started at /home2/alexangu/public_html/wp- content/themes/best-simple/inc/customizer.php:9) in /home2/alexangu/public_html/wp-includes/feed-rss2.php on line 8
Online forums about resolving faulty themes generally say to rename the current theme file so that the theme is reset to default. I tried this by renaming it
best-simple-test, but I get a white screen when I try to reload the webpage.
I have no experience with php, so I have no idea how to fix this error.
Does anyone know how to switch and activate wordpress themes solely in FTP, or how to alter the file
customizer.php to fix the issue?
