Uncaught Error: Syntax error, unrecognized expression

Create modular home page with features module and set Title to Możliwości in features module and publish it in menu (enable Visible).
See JS error on console on home page refresh

Anchor text looks ugly too:
https://my.seerver/#mo%EF%BF%BD-liwo%EF%BF%BD-ci

Same problem if Menu is set to Możliwości in features module.

Checked in grav 1.7.45 + quark theme 2.0.4.

Sounds like an anchors plugin issue. Not core grav?

[pboguslawski]

Checked with all plugins disabled and cache cleared (only Admin Panel plugin enabled).

[rhukster]

Not sure what’s generating anchors then. And what would be using jquery for anchors? Try disabling debugger if enabled, it uses jquery.

[pboguslawski]

Debugger is not enabled & page source contains JS resources:

<script src="/system/assets/jquery/jquery-3.x.min.js"></script>
<script src="/user/themes/quark/js/singlepagenav.min.js"></script>

Ok quark issue. It’s that on page nav menu script.
