Fatal error: Uncaught Error: Call to a member function is_rtl()

Hello,

We have e-Newsletter plugin installed on our site, when we try to create new newsletter or edit existing on customize page we see error. We have latest version of plugin and WP, also we tried to downgrade the plugin version as on another site we have it up and working fine.

Fatal error: Uncaught Error: Call to a member function is_rtl() on null in /var/www/wordpress/wp-includes/script-loader.php:986

We have tried to debug this issue on our site by switch to default WP theme and also by disable plugins, but still no luck. Could you please guide us what the issue could be so we can solve it and use the plugin.

Here is screenshot:

Thanks.

    Hi peter,

    So sorry to hear the inconvenience you are having. I tried to regenerate this on my test site but I could not. So I think, this is your site specific issue.

    As a quick workaround, can you please completely delete this plugin from your site and then install again? Please let us know how it goes.

    I could tell you better about the issue if I could see it live, check your current configuration and make some tests on your site. Would you mind allowing Support Access so we can have a closer look at this?

    To enable support access you can follow this guide here:

    Please confirm here when you are done granting Support Access. I'm looking forward to hearing from you and resolving this issue as soon as possible.

    Have a nice day. Cheers!
    Rupok
