Forum cannot be seen after server updated PHP

[Grammy]

I realize my version of SMF is an older one: 2.0.11.  I have no problem updating it, but I wanted to ask this first.

Everything was fine on the forum until I updated my server's PHP from 5.6.36 to 7.0.33.  Suddenly, I could no longer see the forum.  I reverted that particular domain back to 5.6.36 and everything's back to normal.  Will upgrading the forum from 2.0.11 to 2.0.15 allow me to upgrade that domain's PHP version as well, or is it not compatible with 7.0.33?

Thank you.

As per the Online Manual;

Versions of SMF from 2.0.14 onwards require a version of PHP between 5.4 and 7.1. If you use PHP 5.3 or lower, it is necessary to use SMF 2.0.13 or lower. PHP 7.2 is not supported by SMF at this time.

You can try (and should) update to 2.0.15

Thanks, much!  I'll do that.
