I did a bit more troubleshooting and may have found the solution. First, the steps I took.This time around, I logged directly into my web host with SSH and used wget to download the osTicket ZIP file directly from osTicket. I renamed the current install, extracted the downloaded install to a temporary directory, moved the uploads folder, renamed it to the old install name, and then copied the config file from the old install. Even after all of this, I'm still having rendering issues.Just to be sure, I launched a different web browser, opened a Private/Incognito window, logged into my osTicket install, and clicked around a few times. Eventually, the same issue occurred and styles and scripts were not loading properly.Unfortunately, changing the options in bootstrap.php, in .htaccess, and php.ini would still not display any errors.Not realizing I could, I noticed I could change the version of PHP running on my site. Just to give it a shot, I changed it from PHP 5.3.27 FastCGI to PHP 5.3.27 CGI. After saving the changes, it seems everything is loading properly and without issue.Hopefully that is what was causing the problem but if it shows up again, I'll definitely be back here to look for help again. :)
