installation problem !!

I’m getting the same issue

Dear DESERT_KING and erbrown777,

sorry for my late answer.
The system tried to install the ARC2 library automatically, but it hasn’t the permission to do it. To install the ARC2 library manually please follow the following points:

*) Download ARC2 from https://github.com/semsol/arc2 (https://github.com/semsol/arc2/archive/master.zip) and unzip it.
*) Open the unzipped folder and upload the entire content into the subfolder “arc” in the plugin directory (/wp-content/plugins/climate-change-glossary/arc/).

Thank you,
reegle
