Title: Server Error 500 Upon Login Last modified: August 30, 2016 --- # Server Error 500 Upon Login * Resolved [alexpsba](https://wordpress.org/support/users/alexpsba/) * (@alexpsba) * [10 years, 5 months ago](https://wordpress.org/support/topic/server-error-500-upon-login/) * As I attempt to login to the website [http://www.planetadoradio.com](http://planetadoradio.com), I receive a message that says Server Error 500. When I remove Postman SMTP, I am able to login just fine. Why is Postman SMTP creating this server error? * [https://wordpress.org/plugins/postman-smtp/](https://wordpress.org/plugins/postman-smtp/) Viewing 15 replies - 1 through 15 (of 16 total) 1 [2](https://wordpress.org/support/topic/server-error-500-upon-login/page/2/?output_format=md) [→](https://wordpress.org/support/topic/server-error-500-upon-login/page/2/?output_format=md) * Plugin Author [Jason Hendriks](https://wordpress.org/support/users/jasonhendriks/) * (@jasonhendriks) * [10 years, 5 months ago](https://wordpress.org/support/topic/server-error-500-upon-login/#post-6782940) * I have no idea.

This could be because some feature of PHP that Postman uses is not working correctly or is not configured correctly on your web host. This is extremely hard to debug since its specific to your environment. * Unfortunately, I do not think you will be able to use Postman with your current setup. Sorry about that. * Thread Starter [alexpsba](https://wordpress.org/support/users/alexpsba/) * (@alexpsba) * [10 years, 5 months ago](https://wordpress.org/support/topic/server-error-500-upon-login/#post-6783086) * I figured out the problem and solution. * There is a file on the server which appears to repeatedly keep getting marked as suspected by my server, causing the login panel to be inaccessible. That file is PostmanSmtpDiscovery.php. * PostmanSmtpDiscover.php after a few hours of a fresh installation of Postman SMTP, gets marked by my server as PostmanSmtpDiscover.php.suspected. I removed the .suspected from the end of the file name and that resolved the issue. * I’m not sure if this is a permanent fix, but it appears to have fixed the issue for now. * Note to plugin author: I researched this issue with Postman SMTP and found another couple users who experienced the same issue with PostmanSmtpDiscover.php being marked as suspicious by servers. You may want to look into this. * Plugin Author [Jason Hendriks](https://wordpress.org/support/users/jasonhendriks/) * (@jasonhendriks) * [10 years, 5 months ago](https://wordpress.org/support/topic/server-error-500-upon-login/#post-6783088) * > You may want to look into this. * Well, since it’s _your_ server changing the file then it’s you who needs to look into it 😉 * AFAIK, this file is being targeted by spam malware installed on your site. The malware renames the file in an attempt to disable Postman so that it can send Spam directly. * If your site has been infected you should look into cleaning it ASAP. * [Did you actually read the other post of the other user experiencing the issue](https://wordpress.org/support/topic/fatal-error-require_once-failed-opening-required-postman-configurationpost?replies=10#post-7679300)??

Telling me where the source of the issue comes from would have been just as effective without giving me an attitude. * Plugin Author [Jason Hendriks](https://wordpress.org/support/users/jasonhendriks/) * (@jasonhendriks) * [10 years, 5 months ago](https://wordpress.org/support/topic/server-error-500-upon-login/#post-6783090) * You know I hate snarky comments like that. I’m not giving you attitude. In fact I went to the trouble of putting a winky face and a ‘hope that helps’ and both went right over you head. * There’s no way you can infer my emotional state from the above text, so why don’t you just assume I’m enjoying helping you rather than jump down my throat?

The .suspected has appeared back on the site today. * I have contacted my server and they have stated that they are not the ones making the name change to the file. I have also gone through my security system and scanned for any malware on my system, which also turned up clean. * Here is the report claiming there is not any malware on the site: [http://planetadoradio.com/wp-content/uploads/2015/11/site_scan.jpg](http://planetadoradio.com/wp-content/uploads/2015/11/site_scan.jpg) * Here is what the file on my server: [http://planetadoradio.com/wp-content/uploads/2015/11/suspected_image.jpg](http://planetadoradio.com/wp-content/uploads/2015/11/suspected_image.jpg) * As it doesn’t appear to malware and it doesn’t appear to be my host, is there anything else we can do to stop this file from being renamed? * Plugin Author [Jason Hendriks](https://wordpress.org/support/users/jasonhendriks/) * (@jasonhendriks) * [10 years, 5 months ago](https://wordpress.org/support/topic/server-error-500-upon-login/#post-6783117) * > As it doesn’t appear to malware and it doesn’t appear to be my host, is there > anything else we can do to stop this file from being renamed? * Assuming it is malware, you can change the owner of the file to something other the web user, so that the web user (WordPress) can not rename the file. Depending on your Unix skills you may need to ask your host for help. * ``` sudo chown nobody postman-smtp/Postman/Postman-Configuration/PostmanSmtpDiscovery.php ``` * Another option is to set the file as read-only, but depending on the intelligence of the malware, it may just set it back to writable and then rename it. But it’s worth a try. * ``` chmod 666 postman-smtp/Postman/Postman-Configuration/PostmanSmtpDiscovery.php ``` * A third option is to rename the file to something else entirely, like alex.php. Then you’ll also have to change line 9 of PostmanAdminController.php to reflect your change: * ``` require_once 'Postman-Configuration/alex.php'; ``` * Presumably if the malware can’t find it, it can’t be renamed. * Thread Starter [alexpsba](https://wordpress.org/support/users/alexpsba/) * (@alexpsba) * [10 years, 5 months ago](https://wordpress.org/support/topic/server-error-500-upon-login/#post-6783118) * Thank you for your assistance. I will try these methods and let you know if any were an effective solution. * Plugin Author [Jason Hendriks](https://wordpress.org/support/users/jasonhendriks/) * (@jasonhendriks) * [10 years, 5 months ago](https://wordpress.org/support/topic/server-error-500-upon-login/#post-6783126) * no problem * `:>` * Thread Starter [alexpsba](https://wordpress.org/support/users/alexpsba/) * (@alexpsba) * [10 years, 5 months ago](https://wordpress.org/support/topic/server-error-500-upon-login/#post-6783144) * It looks like renaming the file and changing the permissions did not change the course of the malware. It must be searching for the file by either the documents internal code or through searching directly line 9 on the PostmanAdminController. php * I will try the last method with using UNIX. Lets hope this works. * Thread Starter [alexpsba](https://wordpress.org/support/users/alexpsba/) * (@alexpsba) * [10 years, 5 months ago](https://wordpress.org/support/topic/server-error-500-upon-login/#post-6783151) * I can confirm today that all of those methods do not work. The malware is somehow getting around re-naming the file, changing the permissions, and even the UNIX code saying the WordPress user cannot change the name of the file. * I’m not sure what else to do at this point. * Thread Starter [alexpsba](https://wordpress.org/support/users/alexpsba/) * (@alexpsba) * [10 years, 5 months ago](https://wordpress.org/support/topic/server-error-500-upon-login/#post-6783152) * Alright, I did a fresh installation of the core files of WordPress. Lets hope that might clean out any malware on my site.
