500 Internal Server Error

Every time I update to Yoast 3.6.1 I receive a 500 Internal Server Error. I have tried this on several websites running different themes. I narrowed it down to the Yoast SEO plugin, and when I re-install a prior version of Yoast the site runs fine. I have never experienced a conflict with Yoast before, and am hoping someone can shed some light here. Thank you.

Have you tried to update Yoast SEO to 3.6.1 manually?

@luckcavanagh, I have not done that yet. I will give that a try on a site that is still in development. Thank you. Still concerned as to why this would happen, and curious if others have experienced this?

Experienced the same. Cannot get a working development site of at least one crucial (production) site so have Yoast SEO turned off (really hard to do that after relying for a long time on Yoast SEO). Checked each other plugin and combinations on the site and only after Yoast SEO is turned on the server errors start.

It is strange though that on one site with an older theme (say before 3.2 version of WordPress) all plugins – at least that I use, W3 Total Cache being most suspicient – work OK. So there must be something in latest 3.6 and 3.6.1 releases together with some themes and/or framework (BootStrap 3 in my case).

I’m getting: Fatal error: Class ‘Yoast_Google_WPCache’ not found in /nas/content/live/desamo/wp-content/plugins/wordpress-seo/vendor/yoast/api-libs/google/Google_Client.php on line 90

Rolling back to 3.5 manually fixed it. I’m on Genesis themes on WPEngine, but this is also DOA on my VPS non-Genesis sites as well.

I opened a support ticket with Yoast on Github and will update this thread as I learn more.

I found issue from line 33 of /wordpress-seo/vendor/yoast/api-libs/google/Google_client.php. It is hosting issue. try comment that line and it works
//set_include_path(dirname(__FILE__) . PATH_SEPARATOR . get_include_path());
