Please enable the wordpress debug mode and create a wordpress debug log.
To do so follow the article below:
https://wp-staging.com/docs/enable-wordpress-debug-log-mode/
Do this on your staging site.
Then try to open again the staging site and open the debug.log. It will tell you which plugin is causing the error 500.
Let me know the the error message and I know what’s to do;-)
You can also contact me directly via the error report button
Debug message
Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 72 bytes) in /var/www/html/091918/wp-includes/meta.php on line 846
currently my WP memory limit is set to 256K
Please set the small server settings:
https://wp-staging.com/docs/wp-staging-settings-for-small-servers/
Also add the following code to the wp-config.php:
define( 'WP_MEMORY_LIMIT', '256M' );
Check first if that line is already in that file. If it is just change the value to 256M
If this still does not work I can offer you to check it out. Please send me a mail to support [at] wp-staging.com
If it works I am glad if you let me know about it.
