I am trying to install opencats. While installing I am getting following error. What is the problem?
The errors in the red box is due to the missing external tools.
The errors not in the red box is due to PHP version. The version of opencats you intalled seems not supporting latest php.
You can install https://sourceforge.net/projects/candidats which will support upto PHP 5.6. And it has inbuilt Doc and Docx parser
