500 – internal server error – can't access admin

  • I have the same trouble.
    I’ve tryed everithing you wrote before.
    Disabled plugins via FTP, renamed .htacces (and also tryed to uplad an .htaccess file from an other installation on the same servers), changed the theme, but I still have the problem.
    All the problems are in the admin site. Something works, something doesn’t.
    I can’t access plugins admin, theme admin, wp updates.
    When I publish an article I get 500 internal server error, but the article results published.
    I’ve activeted LOG in wp and I Have logs from server:

    FROM WP:

    I don’t know what happened, I think it was caused by a wp version update, but I’m not sure.

    Please can you help me?

    Thanks.

  • Internal server errors (error 500) are 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 (no Dashboard access required). If that resolves the issue, reactivate each one individually until you find the cause.

    If that does not resolve the issue, try switching to the default theme for your version of WordPress 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.

    If that does not resolve the issue, it’s possible that a .htaccess rule could be the source of the problem. To check for this, access your server via FTP or SFTP and rename the .htaccess file. If you can’t find a .htaccess file, make sure that you have set your FTP or SFTP client to view invisible files.

    If you weren’t able to resolve the issue by either resetting your plugins and theme or renaming your .htaccess file, we may be able to help, but we’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 Matthew, as you can read in my prior message, I’already tryed out everithing you wrote.
    Changed theme: broblem not resolved
    Disabled plugins via FTP: broblem not resolved
    Deleted .htaccess: problem not resolved

    So I activated wp log and also server log.
    In the first message I’ve already included the error messages I found in the server and wp logs.

    Any suggestion based on the errors registered?

    Thanks.

    P.S. All the problems are in the admin panel. Something works, something doesn’t.
    I can’t access plugins admin, theme admin, wp updates.
    When I publish an article I get 500 internal server error, but the article results published.

    I’m having the same problem, may i know if you have been able to solve the problem and in this case in wich way?
