500 Internal Server Error

  • Hello, I’m unable to get the plug-in on the web. An error occurred when SSL enabled:” The server encountered an internal error or misconfiguration and was unable to complete your request.Please contact the server administrator at [no address given].More information about this error may be available in the server error log.”

    If I delete the plugin from the FTP server, delete info in .htaccess and wp-config.php, then the site will be operational again. However, the plugin can no longer be installed in the original version, if it is installed, the previous values are already pre-set for it and the error occurs again after the next setting. Can we fix it somehow? Can plugin values be restored to their original state? Or where is the mistake? I don’t have a problem on other sites. Thank you for the information. Lucy

  • Are you able to access the site using HTTPS ?

    You should only enable the iTSec plugin SSL module after configuring SSL (installing an SSL Certificate) for your site.

    There is a way to get rid of any database stuff the plugin added.

    To prevent any confusion, I’m not iThemes.

    yes, the web has of course allowed SSL certificate and url web address is HTTPS …

    Ok, I see.

    About getting rid of the iTSec plugin database stuff …

    I’m not sure this is going to work in your particular situation, so before following the steps outlined below I would recommend to make sure you have a proper site and database backup.

    The procedure assumes that the iTSec plugin is still registered as installed but deactivated in the database. This is only the case if you did not click the plugin Delete link in the Installed Plugins page. Instead the plugin directory/files were deleted manually as indicated in your topic description.

    So use FTP to manually add the iTSec plugin (7.4.0) directory/files back into the wp-content/plugins directory.

    Then edit the wp-config.php file and add the 2 lines below:

    define('ITSEC_DEVELOPMENT', true);
define('ITSEC_DISABLE_MODULES', true);

    Then log into the WordPress Dashboard (as a user with the Administrator role) and navigate to the Plugins/Installed Plugins page. As expected the iTSec plugin will be listed and the Activate link will probably be available.

    Click on the plugin Activate link. This will activate the iTSec plugin but without activating any modules (We don’t want the enabled SSL module to break things). The ITSEC_DISABLE_MODULES constant set to true in the wp-config.php file will take care of this.

    Once activated click on the plugin Deactivate link.
    Because of the ITSEC_DEVELOPMENT constant set to true in the wp-config.php file the deactivate link acts as if the Delete link was clicked. So all the plugin delete (uninstall) actions in the database are executed. The plugin folder/files however remain !

    Now remove or comment (//) the 2 lines previously added to the wp-config.php file.

    //define('ITSEC_DEVELOPMENT', true);
//define('ITSEC_DISABLE_MODULES', true);

    Click on the plugin Activate link. This will recreate any iTSec plugin database stuff using default values. The iTSec plugin is now in its default state. You’ll need to walk trough any configuration you previously did (except enabling the SSL module).
