Upgraded from 1.5.4 to 1.6.0.8, after installing module, shop breaks

[germinc]

Previously on 1.5.4 I used Ship2Pay, needed the same functionality on 1.6.0.8, so I tried to install Payments2Carriers (http://www.prestashop.com/forums/topic/326247-prestacenter-payments2carriers-free-for-ps-15-and-16/), after installing it, I realized the module does not work. However, it disappeared from the module page. I was using Chrome at this point.

 

At this time, my FO also became unaccessible (white page). I managed to find it in the modules page in another browser (Safari), and I disabled and then deleted it. However, even after doing this, the FO is still a white page.

 

I enabled "Disable Overrides" and the front office works again! I am not sure what is this problem, or how to solve it, so any help through PM or here would be greatly appreciated. 

 

My website is www.movementfirst.sg . It's a fully functional online store, so any changes to it will be done in stages to try what works / or not. 

 

Thanks so much for your help!

Ran the debug and got this:

i looked at the module you downloaded and it only includes a single override class "Module".  It does not include any overrides for the errors you are getting, so I believe the issue you have is unrelated to this module you installed.

 

The errors you provided are complaining about a Tools class override and the Cloudcache module.
