Login "in progres" after upgrade from 3.0.10 to 3.1.4.34

[Zahurcilla]

Hello everyone,

We have: Debian 12, php 8.2 and Teampass 3.0.10.

We are trying to update TeamPass to version 3.1.4.34 or 3.1.4.37 but with both we have the same problems. After updating, we enter the credentials on the login screen and it stays 'in progress'

And in browser:

Can you help me?

I found the solution.
For the first error, I've modified language.php with:

private function loadTranslations() {
$file = "/var/www/html/TeamPass/includes/language/{$this->language}.php";
if (file_exists($file)) {
$this->translations = include $file;
} else {
throw new Exception("Language file not found: " . $file);
}
}

For the second error, I copied the vendor folder again from a fresh 3.1.4 archive.
