Upon updating to Views 2.6, the WordPress Visual editor is not working. If I turn off views everythign works fine, but the site is very reliant on Views. We tested all of our plugins and Views appears the issue. Can you assist?

I discovered this in my logs.

[31-May-2018 01:08:43 UTC] PHP Fatal error:  Uncaught Error: Call to undefined function mb_convert_case() in /home/smallworldvacati/public_html/wp-content/plugins/wp-views/application/controllers/api.php:143

Thank you!

Hi Sammut,

Thanks for reporting this problem.

Unfortunately, I couldn't replicate your issue locally. So, it seems that it's a problem with your installation.

I'm sure that this issue needs to be debugged locally using the debugging tools because we will need to check which part of the code causes the issue.

Anyway, to be able to do so, we will need to work on a copy of your website.
You can use the Duplicator plugin to provide this copy, upload it then share the download link with us here.

I will set the next reply as a private one so that you can provide the information securely.

thanks.

Hi Sammut

Sorry this hasn't been followed up yet.

I can see from the error message that you posted in the initial question that your server appears to be missing the mbstring PHP module.

That's a requirement for Toolset (although we may remove that dependency in an update).

Could you please contact your host and ask them to enable mbstring?

[Sammut]

That fixed it. Thank you!!! 🙂
