So I cannot manage plugins. 2) Is not possible for me to access wordpress/wp-admin/update-core.php (I get a 500 internal server error). So I cannot manage updates. 3) New pages or new post don’t work. existing ones work fine. * The Error Log shows the following errors: * End of script output before headers: admin-ajax.php End of script output before headers: plugins.php …………………… * Hope you can help me. Thank you in advance.

If you don’t have access to your admin panel, try [manually resetting your plugins](https://codex.wordpress.org/FAQ_Troubleshooting#How_to_deactivate_all_plugins_when_not_able_to_access_the_administrative_menus.3F)( 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 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](https://codex.wordpress.org/FTP_Clients), 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. * [alfonso rodriguez](https://wordpress.org/support/users/oscarmica/) * (@oscarmica) * [10 years, 9 months ago](https://wordpress.org/support/topic/internal-server-error-cannot-manage-plugins-and-upsates/#post-6428213) * Hi, I have done all the steps you comment and does not work, I have the same problem Internal Server Error – Cannot manage plugins and updates the log file shows me that every time I try to activate plugins [Mon Sep 07 21:42:07 2015][ error] [client 84.236.167.201:63522] – [http://www.acequiamayor.com](http://www.acequiamayor.com)– End of script output before headers: plugins.php, referer [http://www.acequiamayor.com/wp/wp-admin/](http://www.acequiamayor.com/wp/wp-admin/)[ Mon Sep 07 21:41:49 2015] [error] [client 84.236.167.201:63477] – [http://www.acequiamayor.com](http://www.acequiamayor.com)– End of script output before headers: admin-ajax.php, referer [http://www.acequiamayor.com/wp/wp-admin/](http://www.acequiamayor.com/wp/wp-admin/) Hope you can help me.

This will effectively replace all of your core files without damaging your content and settings. Some uploaders tend to be unreliable when overwriting files, so don’t forget to delete the original files before replacing them. * If that doesn’t work for you, please open your own thread: [https://wordpress.org/support/forum/how-to-and-troubleshooting#postform](https://wordpress.org/support/forum/how-to-and-troubleshooting#postform) Viewing 3 replies - 1 through 3 (of 3 total) The topic ‘Internal Server Error – Cannot manage plugins and updates’ is closed to new replies. ## Tags * [server](https://wordpress.org/support/topic-tag/server/) * In: [Fixing WordPress](https://wordpress.org/support/forum/how-to-and-troubleshooting/) * 3 replies * 3 participants * Last reply from: [James Huff](https://wordpress.org/support/users/macmanx/) * Last activity: [10 years, 9 months ago](https://wordpress.org/support/topic/internal-server-error-cannot-manage-plugins-and-upsates/#post-6428214) * Status: not resolved ## Topics ### Topics with no replies ### Non-support topics ### Resolved topics ### Unresolved topics ### All topics
