I am getting a 502 bad gateway error when clicking on topics. This only happens when I am logged in as admin. The site works fine otherwise. I get this in debug log:

The lines from functions.php:
257 $port = ($_SERVER["SERVER_PORT"] == "80") ? "" : (":".$_SERVER["SERVER_PORT"]);
258 $url = $protocol . "://" . $_SERVER['HTTP_HOST'] . ($with_port ? $port : '') . $_SERVER['REQUEST_URI'];
I'm on godaddy managed WP hosting.
That's very strange that your server doesn't have $_SERVER["SERVER_PORT"] variable. This is a general variable for all servers. Please let me know what serer you use and what is your PHP version. Your server maybe a non-standard or the versions are very old. Here are wpForo server requirements:

Hi Robert,
I've checked the settings. I have:
PHP version 5.6.3
Apache
memory_limit = 512m, max_input vars = 1000, post_max_size =33m, upload_max_filesize = 33m
I can update to the recommended values later today. I'm not sure about the string functions, but I do have mod_rewrite in htcaccess.
I have permalinks set to "post name", but I notice some links are given and extra slash with " post#xxxx. But either links are affected.
Hi,
I've done the following:
added recommended server settings:
memory_limit = 256M
upload_max_filesize = 128M
post_max_size = 128M
max_execution_time = 180
max_input_vars = 10000
I had a wp technician working on it and he determined that is was a server issue, since he was not getting the error by staging. I moved from godaddy to siteground, though the issue still persists, though I was going make the move anyway.
Also recreated .htaccess, but that did not help.
I also had some residual user settings from bbpress that I had installed previously, and I followed their instructions for removing that, it removed the keymaster role from my username but did not resolve the error page issue.
502 bad gateway error when clicking on topics.
I had many of these during development and testing of few sites at the same time.
In my case it was a simple router problem since I was connected via NAT protocol.
A reboot of the modem/router and sometimes disconnect/connect the ADSL line solve the problem for few days until the next boot.
Clearing browser cache helps too.
First time when I called for support [bluehost] they found nothing wrong at their end and they gave that modem/router solution.
