i made a minecraft bedrock 0.15.10 server but i wanna make it so 0.14.3 players can join, how do i do it (im on mobile)

Install the core for version 0.14 for example glowstone in .phar delete the old PocketMine-MP.phar and rename glowstone on PocketMine-MP.phar, if core in .zip

Unarchive this and in settings in startup command paste ./bin/php7/bin/php ./src/pocketmine/PocketMine.php

Hello,

I want to downgrade my server to Minecraft PE version 0.14.3. I was unable to process this via the panel.

Could you please change my PocketMine-MP core file to version 0.14.3 and set the server's PHP version compatible with 0.14.3 (PHP 5.6 or 7.0)?

Thank you!
