I also get this error message on the 404 page…
Notice: ob_end_flush(): failed to send buffer of zlib output compression (0) in /home/marblede/public_html/runbikehappy.com/wp-includes/functions.php on line 4759
Hello Kanger
Maybe this Thread on Stackoverflow will help you:
https://stackoverflow.com/questions/38693992/notice-ob-end-flush-failed-to-send-buffer-of-zlib-output-compression-1-in
If you are using cPanel, disabling zlib.output_compression will help.
Kind regards

I have looked at that page, and implemented the second solution…below…
I wouldn’t recommend disabling the wp_ob_end_flush_all() function entirely, and I definitely wouldn’t turn off zlib.output_compression in your php.ini file. Here’s a better approach that replaces the source code causing the issue, and preserves the underlying functionality:
/**
* Proper ob_end_flush() for all levels
*
* This replaces the WordPress wp_ob_end_flush_all() function
* with a replacement that doesn’t cause PHP notices.
*/
remove_action( ‘shutdown’, ‘wp_ob_end_flush_all’, 1 );
add_action( ‘shutdown’, function() {
while ( @ob_end_flush() );
} );
More details on the cause, and why this is probably the best approach can be found here: Quick Fix for WordPress ob_end_flush() Error`
But maybe I should try the solution mentioned in first reply and just disable it…whereabouts in cpanel will I find zlip.output….?
thanks

yes not fixed the issue, I no longer get the ob_flush error message but it still goes to a 404 page when I update a post….when I disable classic edit, my posts update without any issue….

Hi Kanger
The Classic Editor is working fine here. Do you have a opportunity to check the Webserver logs? Maybe there are some more informations in apache/error.log. The access log will tell you what ressource cannot be found.

can’t see anything showing in web server error logs…
when I click update it’s going to domain/wp-admin/post.php rather than domain/permalink

Spent an hour with host this morning, there are no issues server side, no errors, mod rule etc it is all fine server side and is an issue with the plugin….
when I click on update (on a post) I can a blank white screen (no 404 page or error message) with the link domain/wp-admin/post.php the edit actually saves but it’s annoying that it keeps going to a blank page and doesn’t revert to editing page…
please can this plugin get fixed, really need to complete site asap
Hi Kanger
Some more troubleshooting ideas:
* Delete the Classic Editor Plugin and reinstall it. Make sure that there are no files remaining in the plugins/classic-editor/ Folder after uninstalling.
* Disable other Plugins. Maybe another plugin is incompatible when installed together with the Classic Editor
* Have a look at the .htaccess File. Maybe there are rules genararing this error!
Hope this helps
