Why would you update to PHP 7.2 but use an outdated version of Joomla?

Only using the latest version of joomla you can use php 7. which I recommend using php 7.1

Not entirely accurate: Support for PHP 7 was introduced to Joomla as far back as version 3.5 (March 2016) so PHP 7 support has been around 2 years.

Of course staying up to date with latest Joomla is the obvious action.

@OP
1. Update all your extensions the latest version.
2. If any extensions are incompatible with PHP7.2 then find an alternative.
3. Update to the current Joomla 3.8.6

The current Joomla core works well with PHP7.2.x

Earlier advice is also sound: try PHP7.1.x too
