Internal Server Error ( Premature end of script headers: wp-cron.php)

I would be looking for what ever is register using the WP cron. I could be wrong here but you may have to clear the cron tasks from WP’s database.

For the time being. Try to place the following in your wp-config file

define('DISABLE_WP_CRON', true);

If the problem goes away, you may have to figure our what hook(s) is running and remove the schedule. A good place to refference how cron works with WP take a look at the codex here: https://codex.www.ads-software.com/Function_Reference/wp_cron

My hosting company says;

This is WordPress issue. after wordpress updating many websites have this problems and we are working upon this problem on our network.

And also one of my other hosting says;

This problem is about the compatible theme and wordpress. After updating theme could be crashed and not compatible anymore with wordpress.

I have many wordpress websites and most of them have same problem after i updated wordpress

Is this wordpress updating issue ?

My problem is still exist , my hosting set memory limit up to open website but site is loading damn slow . And i heard many people had problem after upgrade to 4.0.1 . How can i fix this ?

Sry for the late reply. It could be a issue with the WP update but I would look elsewhere first. Hosts tend to point fingers and it could very well be a WP update issue with your host. Being that it is not widespread what is your host?

You mentioned most of your sites have this issue. It could be the configuration that your host is running.

I am hosting my website on 3 hosting company. Godady,natro and justhost. On godaddy and natro i have this issue. Godaddy says this updating problem and also new wp update is not compatible with your theme. Natro said our netwoork team checking it up but no answers till now. I dont know what to do. I didnt have databases back up. When i check my error.log file on natro it says the problwm i said on title of this post.

Your database is still there so no worries. I would go create backups no though. There was no other errors in file before the one you are stating?
It could be the cron job is in a loop maybe and hitting the limit of memory, execution time etc. but the error above is just stating the end result.

What if the memory limit set to for your host?

You mentioned that the hosting company said something about the theme not being compatible.. May contacting the theme author may help as well.

I did but no answer. They say there is no problem because its not only theme i got this error. I use many different theme and most of them are same. Memory-limit is 64MB on hostings. I got one more error as well i am gonna copy it here.

I didnt have any problem before upgrading and working well my websites. I just upgraded and the next day i checked them up they were all damn slow.

I blocked cron process by typing;

`define(‘DISABLE_WP_CRON’, true);

in wp-config.php but didnt work.

By the way when i changed my theme the site is being okay. But i changed eveything on that theme and i dont wanna change my theme.

Pffff what an update!

Hi,

my problem is not exist anymore. My hosting company made some process and now its okay. They say it was general problem and we worked on our servers and now my websites open fastly..

who has this problem, better talk with hosting company

Your outcome is a common response from hosting companies. Glad it is working for you now.

Hi Deterjan

I have the same problem. And my hosting provider says also it is on WordPress. Do you know what your hosting company exactly has change so it works now? So I can ask/say that to my hosting company …that they must change that…

Hi,

I recognised later it was not because of hosting. What’s your website’s link. I am gonna check. And did you update anything such as plugin or wordpress?

Hi,

I update WordPress to v4.3.1. and ‘big’ plugins as Yoast SEO, Jetpack and WooCommerce
and a number of ‘small’ plugins but the error started before (the most updates) in both index.php as cron.php (so out of the blue)
