Modules and Services not opening

[dreamphonecases]

Hi guys!

Yesterday I have posted an issue which did not allow me to finish my installation process. It stopped at 67% with modules installation error. ( https://www.prestashop.com/forums/topic/571479-modules-installation-error-during-initial-installation/ )

With my surprise today I woke up and saw my shop up and running.

However, when I log in into my back office and press on Modules and Services (subcategory!! others do work - modules and themes catalog, positions, payments) I get the following error:

[PrestaShop] Fatal error in module file :/var/www/vhosts/dreamphonecases.com/httpdocs/modules/statsdata/statsdata.php:

syntax error, unexpected '['

Did anyone have a similar problem or do know how to fix this issue? 

Thank you for your help!
