After the 1st failures I have tried again. I uploaded my back up copy of the store and started fresh at 1st I could install and make changes to the payment modules with no issues. After following the installation directions for Square Payment Module, I can no longer see any installation or make changes to the payment modules and the Square module is not listed as in the image in the previous post. I now have 4 new debug logs which I don't understand:

[07-Aug-2017 23:34:16 America/Detroit] PHP Parse error: syntax error, unexpected '[', expecting ')' in /home/sammirah/public_html/webstore/includes/languages/english/modules/payment/square.php on line 34

My assumption is I need to change a [ to a ) somewhere on line 34 in the square.php file but I don't want to mess anything else up, if that is not what it means. Please advise.
