Hi
This sounds very much like a coding issue and nothing to do with WAMPServer itself.
We do not suppost the code you write in PHP, only the environment.
Please remember that PHP7 is very different to previous versions of PHP and therefore you should look at the
Migration NotesAlso it is impossible to to debug code without being able to see it.
