Hi,
It is totally impossible to answer your question with certainty.
You may be using functions that have changed with PHP 5.5.
The mysql functions are obsolete with PHP 5.5 and 5.6 are deleted with PHP 7.0.0; you have to use mysqli.
Anyway, even on your website, your hoster must pass on new versions of PHP, so it is a good thing to check it work correctly with a later version of PHP.
Whatever the PHP version used, if you "recopy" your site on Wampserver, it is essential to use VirtualHost like your hoster:
