Issues with the UDDEIM template.

Problems with the UDDEIM template.
UDDEIM works well in the sending and receiving of private messages, that is, it works well in workability.
I enclose the images where the list that should go horizontal is shown vertically: "only with icons" or "icons and text".
The Message box configuration (cols / rows and width) does not work in the template. See in the attached images.

- JOOMLA 3.8.2
- pkg_communitybuilder_2.1.3+build.2017.11.16.20.21.51.1a2f01fa1.zip
- uddeIM 4.0

I managed to correct the errors in the template.
Modified the files:

• uddeim.css
• includes.php

Hi, i know it's been a long time ... but how did you correct the mistakes? could you tell me which code to modify? thanks
