@petrchutny You are getting 500 error code, Can you please enable debugging mode, Please add following lines to wp-config.php just before where it says: /* That’s all, stop editing! Happy publishing. */
define( ‘WP_DEBUG’, true );
define( ‘WP_DEBUG_DISPLAY’, false );
define( ‘WP_DEBUG_LOG’, true );
Then try to optimize again
A debug.log file should be created inside wp-content folder,which should contain error information in it, Please share the file with us.
Thanks,
Harshad
Thank you @bornforphp.
I have enabled the debugging as instructed on two sites. Then I’ve started the optimizing process again, and on both sites, it failed again. But no debug.log file was created in the wp-content folder on both sites, unfortunately. I’ve set 777 permissions to wp-content folders and also created the debug.log file manually, didn’t help – no logs there. The error is still the same.
Thanks for your time on this,
Petr
Debug doesn’t normally write to the wpcontent folder. Try checking the main wordpress install folder.
@bornforphp I’ve finally found the debug.log in wp-content, here it is: https://pastebin.com/d8rSUtuy
Here is the log file from WP Optimize itself: https://dsh.re/9c2a2
Thank you for your comment @cmba but there was no debug file in the WordPress install folder.
