Hello,
If you are familiar with the debugs logs can you enable the logs so that you can see when the errors comes from, try debugging and and debugging log on.
e.g. open your WordPress project directory, and open wp-config.php, then you will find
-> define(‘WP_DEBUG’, false);
make this true, and also make one more line after this for debugging,
-> define( ‘WP_DEBUG_LOG’, true );
then after check your site, you can see the error logs in project/wp-content folder and the file is debug.log
after completing do not make false debugging.
May this will help you.
