Hi,
1) Internal server errors (error 500) are generic errors and often caused by plugin or theme function conflicts, so if you have access to your admin panel, try deactivating all plugins. If you don’t have access to your admin panel, try manually resetting your plugins. Please refer following guide to deactivate all plugins:
https://codex.wordpress.org/FAQ_Troubleshooting#How_to_deactivate_all_plugins_when_not_able_to_access_the_administrative_menus.3F
If that resolves the issue, reactivate each one individually until you find the cause.
2) If that does not resolve the issue, try switching to the Twenty Fourteen theme to rule-out a theme-specific issue. If you don’t have access to your admin panel, access your server via FTP or SFTP, navigate to /wp-content/themes/ and rename the directory of your currently active theme. This will force the default theme to activate and hopefully rule-out a theme-specific issue.
3) If you weren’t able to resolve the issue by either resetting your plugins and theme or renaming your .htaccess file, it’ll need a more detailed error message. Internal server errors are usually described in more detail in the server error log. If you have access to your server error log, generate the error again, note the date and time, then immediately check your server error log for any errors that occurred during that time period. If you don’t have access to your server error log, ask your hosting provider to look for you.
Thanks,
Hi!
Thanks for the answer. I tried to do everything you told me, but no luck..
I can’t enter in my wp-admin panel, I just can enter in cpanel and I have no idea how to fix it, I’m a beginner with these things 🙂
