Tabs not showing

Turned debug on and getting this error message. I’ve already downloaded the plugin from .org and re-installed it and still getting this error.

Fatal error: Call to undefined function mb_strtolower() in /home/gf/public_html/wp-content/plugins/breadcrumb-navxt/class.bcn_admin.php on line 502

Here is the server info – we are running this on 2 different sites both with:

PHP Version: 5.5.19
MySQL Version: 5.6.23
Webserver Info: Apache/2.4.10 (Unix) OpenSSL/1.0.1e-fips mod_bwlimited/1.4

Both sites having the same problem.

I’m getting this issue too – no save buttons or tabs

Our server admin came back with this:

To fix the issue you need to compile PHP with the mbstring module/lib installed (this wasn’t previously). This allows PHP to handle multibyte strings (japanese characters and alike), which was the problem with the string replacement on the breadcrumb.

Hope that helps someone else.

Breadcrumb NavXT uses the mb_ string functions since it supports multibyte characters. There is a support library that should have loaded to take care of this. However, it apparently is not loading in on that content. I will look into this more, however the real solution is to get your server to have multibyte string support.
