Hi @arunschandran,
We’re sorry for the trouble you’re experiencing with our plugin. We expect few more information about your setup. This might help us replicate the issue on our end:
1. Are all your non-Yoast plugins and themes also updated?
2. Can you confirm you are using the latest WordPress 5.5.1? Please know that if you are using an older version of WordPress Core you may experience unexpected behavior with Yoast. This guide explains more: https://yoast.com/why-we-dont-support-old-wordpress-versions/.
3. Does your website meets the plugin requirements?
4. If you deactivate all non-Yoast plugins and switch to a standard theme like Twenty Nineteen does the issue resolve?
Test this on your development or staging site, if you have one. If not, we recommend using the Health Check & Troubleshooting plugin. This plugin allows you to run a conflict check without affecting normal visitors to your site.
As we can imagine that you’re unfamiliar with checking for conflicts, we’d like to point you to a step-by-step guide that will walk you through the process: How to check for plugin conflicts.
We look forward to hearing from you.
Hi @suascat_wp
Thank you for your quick response.
1) Yes
2) Yes
3) Yes
4) I deactivated all non-Yoast plugins and switch to a standard theme. But issue is still there
And I checked heath check and there was an issue I fixed it. But still I can’t see the site homepage
Thank you
@arunschandran Thanks for your reply and for the additional information.
The error itself is stating that a class is not found and this usually happens when the plugin files are cached and some old files are still used after updating the plugin. On occasions, this causes temporary errors that resolve themselves once the cache has been cleared.
To resolve this, can you please try clearing the cache from your theme, plugin, server and CDN (e.g. CloudFlare) before and after updating Yoast SEO? If you are not sure how to clear the cache from a theme or plugin please speak to those authors. If you want to clear cache from the server, please speak to your host provider.
If after performing those steps you still receive the error, it’s also possible that something is going wrong during the update procedure which is causing the plugin’s files to become incomplete or damaged. If that is the case, as a workaround you can also perform a manual update of the plugin. We have instructions on how to upgrade the plugin manually at the following link: https://kb.yoast.com/kb/how-can-i-update-my-free-plugin/#ftp. You will need an FTP program such as FileZilla and your FTP details, which can be obtained from your host provider.
We are going ahead and marking this issue as resolved due to inactivity. If you require any further assistance please create a new issue.
I did what you suggested and issue is still there
