Login widget causes "Notice: compact(): Undefined variable: options" for anonymous users

Problem

When I access my Pagekit site as anonymous user, I get an Whoops, looks like something went wrong. error in an unstyled page. After I enable the debug mode, I see the following backtrace.

1. in login.php line 25
2. at ErrorHandler->handleError('8', 'compact(): Undefined variable: options', '/home/cu1oo7s7/public_html/app/system/modules/user/widgets/login.php', '25', array('widget' => object(Widget), 'app' => object(Application), 'user' => object(User), 'redirect' => '@page/1', 'last_username' => null))

Visiting the site as administrator doesn't cause any issue; the same is true when I disable the login widget.

Technical Details

• Pagekit version: 1.0.18
• Webserver: Apache
• Database: MySQL 5.6.26-cll-lve
• PHP Version: 7.3.8

I changed the PHP version used from the site to PHP 7.2.21. Now the homepage and the login widget are visible. It seems the issue is caused from the PHP version.

I will check if there are PHP extensions not enabled when I use PHP 7.3, but I think the problem is incompatibility with PHP 7.3.

These are the extensions PageKit lists for PHP 7.3.

Core, date, libxml, openssl, pcre, sqlite3, zlib, bz2, calendar, ctype, curl, hash, filter, ftp, gettext, gmp, SPL, iconv, pcntl, readline, Reflection, session, standard, shmop, SimpleXML, mbstring, tokenizer, xml, litespeed, intl, uploadprogress, gd, fileinfo, sockets, uuid, zip, xmlwriter, yaml, json, igbinary, exif, apcu, imap, mysqlnd, PDO, pdo_mysql, gmagick, dom, pdo_sqlite, Phar, xmlreader, posix, xsl, Zend OPcache

These are the extensions listed by PageKit for PHP 7.2. The difference is mostly extensions that cPanel doesn't show for PHP 7.3, which I cannot enable.

app/system/modules/user/widgets/login.php has line return $app['view']('system/user/widget-login.php', compact('widget', 'options', 'user', 'last_username', 'redirect'));. However, options is undefined and thus causes the error. Changing the line to return $app['view']('system/user/widget-login.php', compact('widget', 'user', 'last_username', 'redirect')); will solve the issue.
