Theme compatible to Prestashop 1.5.5 to 1.5.6.2+ used in a 1.5.4.1 shop

[darnux]

Hello.

 

I've been given a Prestashop backup from a possible customer in order me to install in my server and take care of his online shop.

 

I want to be sure everything is ok before I accept the job. I have found that the shop runs Prestashop 1.5.4.1 and the theme, once I found it on theme forest searching by its name, says it's compatible from 1.5.5 to 1.5.6.2+

 

My question, are there known issues in this situations? The theme looks awful, and I want to be sure I can fix it from its options, before accepting the job.

 

Sadly, the shop owner don't have the theme installer, and can't ask for it to the former developer, because personal problems.

 

Thanks in advance for your help
