500 or 503 Error when activating Jetpack plugin

this just hit me 2 https://mycascadescenter.org/ but it’snot random, happens every time…it’s disabled right now…and nothing in errlog

@airdrummer I’m not using right now. Uninstalled it. And waiting for an update.

Hi there!

Since this is a 500-level server error, we’ll need to take a look at your logs to see if we can figure out what the issue is. To get started, please add the code shown at the link below to your site’s wp-config.php file:

https://gist.github.com/56b19f31f2d5a6265a10bebe09e03314

Your wp-config.php file may already include a line that says this:

define( ‘WP_DEBUG’, false );

If so, you can remove it, and replace it with the code at the link above.

If you’re not sure how to edit this file, you can ask your hosting company for help. They should also have documentation explaining how to edit files from your site using FTP or a File Manager in your admin panel.

Once you’ve made those changes, attempt to load your site again. This should cause a 500 error or a completely white screen just like before, but this time the error message will be captured in the WordPress logs.

After that, access your site via FTP or via your File Manager again and check the wp-content/debug.log file for errors.

You can send us those logs in a reply to this email, and then replace this:

define(‘WP_DEBUG’, true);

… with this:

define(‘WP_DEBUG’, false);

… in the code you added to wp-config.php earlier.

Once you’ve sent us the logs, you can sometimes fix this error by simply reinstalling Jetpack, so that’s the first thing to try.

To uninstall Jetpack, start under Plugins > Installed Plugins. If Jetpack is active, click Deactivate to disable it. Then click Delete to remove it from your site.

If you can’t log into your site’s WordPress dashboard, you can remove Jetpack by using FTP to connect to your site. (Your host will have instructions on how to do this.) Once you’ve connected via FTP, browse to this folder: wp-content/plugins. Inside there should be a folder named “jetpack”. Delete it to remove Jetpack from your site.

Once it’s been uninstalled, you can reinstall it under Plugins > Add New. Simply search for “Jetpack by WordPress.com” and click Install Now like so:

When Jetpack is done installing, click Activate. Click the large Connect button to reconnect:

In most cases that has resolved the issue for our users, but if not, another thing to check is the version of PHP your site is running on. WordPress suggests PHP 7.0 or above, but 5.6 should also work. If you have anything lower than 5.6, I would suggest contacting your host about updating your PHP installation to see if it helps improve the situation.

Let us know if either of those solutions work for you.

Problem Solved Automatically. Now working fine.

again I’m facing this problem but this time not using any plugin
@airdrummer how did you resolve? @lamdayap

sorry, i had resolved this in email w/my shared hosting provider: jetpack v5.1 requires php>=5.6, discovered & set Current PHP version in my cpanel’s PHP Selector, ymmv;-)

u’d think jetpack would check

if ( PHP_MAJOR_VERSION > 5
  or (PHP_MAJOR_VERSION == 5 and PHP_MINOR_VERSION >= 6) )
   ok then...
