Hello Radek!
The white screens, the missing Elementor button, and the 500 server errors after an update indicate that something in your WordPress environment is failing. Without an older backup, the best approach is to troubleshoot the live site to pinpoint the exact cause.
To get more details on the 500 error, you need to check your server’s error logs. A 500 error is a generic message, but your server records the specific failure. You can find the error_log file in your hosting control panel. Alternatively, you can enable debugging in WordPress by editing your wp-config.php file and setting WP_DEBUG to true, along with WP_DEBUG_LOG to true. This generates a debug.log file in your wp-content folder detailing exactly which file or process is causing the crash.
One possibility to investigate is your site’s memory limit. Elementor and WooCommerce require significant resources. You can test if this is the issue by increasing your PHP memory limit to 512M. You do this by adding define( ‘WP_MEMORY_LIMIT’, ‘512M’ ); to your wp-config.php file right before the line that says to stop editing.
Another area to check is your website’s caching. The need to refresh the page and the disappearing edit button can sometimes be caused by old cache data conflicting with the new update. You should completely clear any caching plugins you have installed. Additionally, clear your server cache from your hosting dashboard and purge your CDN if you use one. Inside your WordPress dashboard, go to Elementor Tools and click Regenerate Files and Data.
Finally, investigate potential plugin conflicts. A different plugin might be incompatible with the new WordPress version. Try deactivating all plugins except Elementor and WooCommerce to see if it allows you to publish without the 500 error. If it works, reactivate them one at a time until the error returns to identify the conflicting software.
We are looking forward to your reply.
Kind Regards,
