myDBR 4.7.0 is fully compatible with the new PHP 7 and gains the benefits of it (2x faster execution and lower memory requirements). To update myDBR to PHP 7 compatible version, use following guide:
Check your ionCube version. PHP 7 requires ionCube 6.x version of the loader to be installed. (You can also use ionCube 6.x with earlier PHP versions). Check also that you are using ChartDirector 6.0.
If you are running PHP 5.6, run the automatic updater twice. The first update round updates myDBR to 4.7.0 and the second one will pick up the PHP 7 compatible myDBR version. After the updates you can switch to PHP 7.
If you are running PHP 5.5 or earlier you have two choises:
1) Update to PHP 5.6 and use the automatic updater (as described above)
2) Download PHP 7 compatible version of myDBR and do manual update. See myDBR documentation for manual update. All your reports will remain intact also during the manual update
