Many errors in gallery:
1- the message appears:
cpg1.5.48 has been released. It's a security update for Coppermine in order to counter recently discovered vulnerabilities. It is important that all users who run version cpg1.5.44 or older update to this latest version as soon as possible.

I don't know how to do this, like someone explain to me how I do it?

So looks like you're running Coppermine v1.5.34 and your host has upped the PHP version.  Can you confirm what version of PHP your server is running? If your server is running PHP 7.x.x then you'll need to upgrade to Coppermine 1.6.06 to make it compatible.
