I encountered an issue while updating plugins on my WordPress website. The update process halted, and upon refreshing the page, I received the error message “There has been a critical error on this website.” Unfortunately, I’m unable to access wpadmin, and attempts to resolve the issue by renaming the plugin folder in my host’s File Manager have been unsuccessful.
my sister who is a consultant says critical errors can occur if your website runs out of memory. You can try increasing the PHP memory limit in your wp-config.php file.
Try renaming the entire plugin folder instead; this usually resolves the issue for us (99% of the time). After that, perform a restoration (we use the All in One WP Migration plugin to handle this in these situations).
You may also try restoring the hosting backup (which we have with our SiteGround hosting) if that doesn’t work.
To avoid having your production sites “suffer” from the outage, I would advise you to set up staging sites ahead of time for updates.
about this error lets get the specifics It may be necessary to seek assistance from a WordPress developer or your web hosting provider for more advanced troubleshooting. They can help identify the specific cause of the critical error on your website.
