Fail to run TT RSS web interface


Hi guys,

I am getting a weird error when trying to run my installation of Tiny Tiny RSS. The feeds seems to be updating, but when i run the URL, the page shows the error below. Does anybody have any idea what might be wrong?

<?php if (file_exists("install") && !file_exists("config.php")) { header("Location: install/"); } if (!file_exists("config.php")) { print "Fatal Error: You forgot to copy config.php-dist to config.php and edit it.\n"; exit; } // we need a separate check here because functions.php might get parsed // incorrectly before 5.3 because of :: syntax. if (version_compare(PHP_VERSION, '5.3.0', '<')) { print "Fatal Error: PHP version 5.3.0 or newer required.\n"; exit; } set_include_path(dirname(__FILE__) ."/include" . PATH_SEPARATOR . get_include_path()); require_once "autoload.php"; require_once "sessions.php"; require_once "functions.php"; require_once "sanity_check.php"; require_once "version.php"; require_once "config.php"; require_once "db-prefs.php"; require_once "lib/Mobile_Detect.php"; $mobile = new Mobile_Detect(); if (!init_plugins()) return; if (!$_REQUEST['mobile']) { if ($mobile->isTablet() && PluginHost::getInstance()->get_plugin("digest")) { header('Location: backend.php?op=digest'); exit; } else if ($mobile->isMobile() && PluginHost::getInstance()->get_plugin("mobile")) { header('Location: backend.php?op=mobile'); exit; } else if ($mobile->isMobile() && PluginHost::getInstance()->get_plugin("digest")) { header('Location: backend.php?op=digest'); exit; } } login_sequence(); header('Content-Type: text/html; charset=utf-8'); ?> Tiny Tiny RSS

if you see <?php tags in the output your server has php disabled or misconfigured, might want to look into that


Thanks for the info man. I’m on a Synology Diskstation, and as far as I can see, Php56 and php7 is installed, so its odd.


This isn’t a support forum for web stacks or NAS appliances, but if you’re seeing PHP (like fox said) it means the web server (Apache, Nginx, etc.) is not passing PHP files to the PHP interpreter. In Apache it depends (mod_php or pass it externally with CGI or something). In Nginx you probably want to use fastcgi to PHP-FPM.

Please find Synology support site because they’d certainly be able to help you better than us here.

Also, moving this thread to unsupported but if someone wants to post a solution they’re welcome to. No guarantees though.
