When you see the php file via web browser, it will display something like:

/homepages/35/d120461223/htdocs/[your path to myBB installation]

This is the absolute path to use.

Good luck!

I was able to solve this problem. One way to know your absolute path is to use php function, realpath(). You can create a php file, include echo realpath(‘./’) in the file, and upload to your mybb directory.
Then type the file in your browser.
This is the code that I used to know the absolute path for mybb installation.
<?php echo realpath('./'); ?>
I hope this info is helpful.
