When I install the module in my Drupal site and try to enable the module Content Timeline , I get this error: 

Parse error
: syntax error, unexpected ‘[‘ in /home1/tremat/public_html/ecran3/sites/all/modules/content_timeline/content_timeline.module on line 147

I enabled many more module on the site and never had a problem.

How can I get the module to work?
Thank you!
