Hello wordpress community,

we are facing the issue, that the save-button in wordpress is sometimes greyed-out (and stays that way). As far as we observed this, this usually happens on the auto-save.

I am aware, that the usual reason for this would be errors in the code, but there are no errors logged in the fpm- or apache-logs. There is also no indication of a timeout (ie no 408 response code).

The wordpress instance currently has 512 MB of RAM and does not use all of it. It also has more than enough CPU-Power.

My assumption is, that there is either a timeout on the auto-draft-saves or an error of some kind, that does not get logged.

So how would i be able to confirm this/find the error? turning on WP_DEBUG is not an option tho, as there is too much traffic on this backend.

thank you,

best regards,

scones

  • Any console errors?

  • As this happens not all the time, but randomly, there is never a console open. especially since the users of that interface are more focused on the articles and would be rather distracted by an console. but i might consider capturing all js errors and passing them along (similar to what newrelic does)

This can happen as you said there are some errors in code or if there is long or duplicate queries. Try to debug it with Query Monitor. Same reason if Safe button takes longer to get active.

  • the problem is occuring randomly so this excludes: errors, long running/duplicate queries. also the button does not take longer but stays greyed out.
